Category: Food & Drink
Description: Stored referral listing for Itsu. The stored route is the code/label 28855; the exact referral URL field is blank and must remain blank. The third-party listing says that a new Itsu app user who registers with a referral code may receive a bonus butterfly (loyalty stamp). Itsu's official pages confirm the underlying loyalty programme and its rewards, but do not publish code 28855 or a universal referral-code rule on the pages reviewed. Treat the bonus as conditional and verify it in the app before relying on it.
Importantqualification: Do not replace the blank URL with an app-store link, a shortened link, or another referral URL. If the registration screen provides a referral-code field, use 28855 exactly as stored.
Label: 28855
Referralcode: 28855
Reward: Special Offer
How to claim the offer
- 1Install the official Itsu rewards app from the legitimate app source linked by Itsu, or open the app if it is already installed. Itsu's loyalty page describes the programme as app-based and says customers should scan the app at an Itsu kiosk or till.
- 2Create an account with an email address you can access. Complete any email verification or other identity prompts. If you already have an Itsu loyalty account, do not assume you qualify as a new user: check whether the app accepts a referral code before creating a second account, because duplicate accounts can make reward tracking and support more difficult.
- 3During registration, onboarding, or the referral prompt, enter the stored code 28855 exactly. Because the stored referral URL is blank, the code/label is the stored route. If no referral field appears, do not invent a URL or substitute a different code; record what the app actually offers and contact Itsu support if the referral listing promised a reward.
- 4Before finishing signup, read the confirmation or reward wallet screen. Look for a bonus butterfly, a referral acknowledgement, an expiry date, or specific qualifying instructions. Save a screenshot showing the code entry and any confirmation. The official Itsu pages reviewed do not independently confirm that 28855 produces a bonus, so this in-app evidence is important.
- 5If the offer requires a qualifying purchase, make it at a participating UK Itsu restaurant and scan your app barcode at the kiosk or till before paying. Itsu says a transaction of £5 or more earns a butterfly; the official terms clarify that the threshold is £5 or more and that only in-store UK restaurant transactions count for loyalty butterflies.
- 6Check the app after the purchase. Itsu says a butterfly can take up to one hour to appear. If it is missing, keep the receipt and submit it through Itsu's contact form, including the account email or loyalty number, restaurant, date, amount, and a screenshot of the referral confirmation.
- 7Use any issued reward from the app before its expiry date. Itsu's official FAQ and terms say loyalty vouchers generally expire 90 days after issue, may appear with a countdown six days before expiry, and must be applied at checkout before payment. Confirm the individual voucher terms because promotional rewards can differ.
- 8At redemption, scan the app at the till or kiosk before payment and select the relevant reward. Check stock and eligible menu items first; Itsu says it is not responsible if a reward item is unavailable. Do not expect the referral reward to be exchangeable for cash or usable through delivery or on Itsu grocery products.
Your referral benefit
The practical benefit of the stored Itsu referral offer is a possible head start in the Itsu rewards programme: the referral listing says a qualifying new app user may receive one bonus butterfly. A butterfly helps move an account toward Itsu's ordinary loyalty milestones. Itsu's official loyalty page says customers receive a butterfly for each £5 order scanned through the app, while the official FAQ specifies the rewards: three butterflies unlock a free snack or drink, five unlock free gyoza, and seven unlock a free Itsu meal. The official terms add that butterflies are collected in UK Itsu restaurants, vouchers are single-use and non-transferable, and loyalty vouchers generally expire 90 days from issue. Thus, if the referral bonus is accepted, it can shorten the path to a normal loyalty reward, but it is not the same thing as an immediate free meal. It may also be valuable for the app's other features, including a welcome gift, birthday treats, app-exclusive prices, and notifications or limited offers. Those extras are programme features, not guaranteed consequences of code 28855. The referral listing also mentions a first-app-order discount, but that statement conflicts with the more specific bonus-butterfly description and is not confirmed by the official Itsu pages reviewed; do not treat a first-order discount as guaranteed.
Before you claim
- Eligibility: confirm that you are a genuinely new eligible Itsu app user if the app or referral listing says so. A person who already has an Itsu account, has previously redeemed an onboarding offer, or tries to create duplicate accounts may be rejected. Itsu's published pages do not state the exact eligibility rule for code 28855, so the app's live prompt controls.
- Route integrity: the stored referral URL is blank. Use only the label/code 28855 if a code field is shown. Never silently correct it, replace it with another code, or infer an unrecorded URL.
- Offer verification: check that the app explicitly acknowledges the referral and shows the bonus butterfly or other reward. The official Itsu loyalty and terms pages explain butterflies and vouchers but do not name code 28855; this is a material verification gap.
- Qualifying spend: for ordinary butterfly earning, spend at least £5 in one transaction and scan before paying. The terms describe the £5 threshold for UK Itsu restaurant transactions; delivery, supermarket grocery purchases, and unscanned purchases should not be assumed to qualify.
- Location and channel: use a UK Itsu restaurant, kiosk, or till. Official loyalty vouchers cannot be used on Itsu grocery products or through delivery channels. Gift cards and other promotions have their own exclusions, so do not generalise their rules to this referral.
- Timing: allow up to one hour for a butterfly to appear. Check the voucher expiry date; official loyalty vouchers generally expire 90 days after issuance and may disappear when expired.
- Checkout: apply the voucher and scan the app before payment. Rewards cannot normally be combined with another offer, are single-use, non-transferable, and cannot be exchanged for cash. Review the individual voucher for item exclusions, minimum spend, and any store or time restriction.
- Availability: free snack/drink, gyoza, or meal choices depend on the published eligible-item lists and stock. The official terms exclude categories such as alcohol, and the meal reward excludes alcohol, sharing platters, bundles, and breakfast items. Ask staff before ordering if the item is borderline.
- Evidence and support: retain the receipt, code-entry screenshot, account email, loyalty number, restaurant, and timestamp. If the reward fails, use Itsu's contact form; Itsu specifically asks for the account details, shop, and voucher involved.
Itsu referral questions
What is the Itsu referral code?
The stored referral code/label is 28855. The exact referral URL is blank. Use 28855 only if the official Itsu app or registration flow presents a referral-code field; do not substitute a different link.
What exactly is guaranteed by code 28855?
Nothing can be treated as universally guaranteed from the official sources reviewed. The referral listing describes a possible bonus butterfly for a new Itsu app user. Itsu's official pages confirm how butterflies work, but do not publish code 28855 or confirm its referral reward. Check the live app confirmation before spending.
Is this an instant free Itsu meal?
No. Even if the bonus butterfly is credited, it is one step in the loyalty programme. Itsu's normal milestones are three butterflies for a free snack or drink, five for free gyoza, and seven for a free meal. The referral listing's separate suggestion of a first-order discount is not confirmed by Itsu's official pages.
Who should try the offer?
It is most plausible for someone who has not previously created or used an Itsu rewards account and can complete any live onboarding requirements. Existing members should check their account first rather than opening duplicates. Because Itsu does not publish the 28855 eligibility rule, the app's acceptance message is decisive.
Where do I enter 28855?
Enter it in the referral or promo field shown during Itsu app registration or onboarding. If no field is displayed, do not force the code into a normal voucher field and do not invent a URL. Contact Itsu support with the listing details if you believe the prompt is missing.
What purchase earns an ordinary Itsu butterfly?
Itsu says to scan the app at a kiosk or till when spending £5 or more. The official terms specify UK Itsu restaurants and say the threshold is £5 or more in a transaction. Scan before payment; a purchase that was not scanned may require receipt-based support.
How quickly should the referral butterfly or purchase butterfly appear?
Itsu's terms say vouchers may take up to one hour to appear, and its FAQ says missing transaction rewards can be investigated through the contact form. Check the account after that period and keep your receipt and screenshots.
What do three, five, and seven butterflies provide?
The official FAQ says three butterflies provide a free snack or drink, five provide free gyoza, and seven provide a free Itsu meal. The exact eligible choices and exclusions are listed in Itsu's terms and can change, so read the voucher in the app.
How long do Itsu loyalty vouchers last?
Itsu's FAQ and terms state that rewards generally expire 90 days after they are issued. The FAQ says a countdown appears six days before expiry. Use the date shown on the individual voucher, since a campaign-specific rule may be narrower.
Can I use the reward on delivery or Itsu supermarket products?
Do not assume so. Itsu's official loyalty terms say loyalty vouchers are redeemable in-store at UK Itsu restaurants and not for Itsu grocery products or delivery channels. The referral bonus should first be converted into the app voucher, whose own terms should be checked.
Can I combine the reward with another discount?
Generally no. Itsu says loyalty vouchers cannot be used with another offer, are single-use, non-transferable, and must be applied before payment. A particular campaign can state an exception, so read its on-screen terms.
What if my free item is unavailable or the code fails?
Itsu says it is not responsible if reward items are out of stock. If the code was accepted but the reward is missing, or checkout rejects a valid voucher, contact an Itsu team member and then use the official contact form. Include your email or loyalty number, shop, voucher, receipt, and screenshots.
Does signing up also give a welcome or birthday reward?
Itsu advertises a welcome gift and birthday treats as app features. Birthday eligibility requires adding and verifying a birth date in the app; the terms describe a birthday gyoza voucher with a 90-day expiry and eligible gyoza conditions. These are separate programme benefits, not a confirmed extra reward for code 28855.

Raise
£10 Free
The directory record for this entry is **£10 Free**. The preserved referral code/link is **Referral link**, and the exact referral URL is **https://slide.app.link/b5gkzZd5t6b**. Use that address exactly; do not replace it with a search result, a copied code, a URL shortener or a different person’s link. When checked on 2026-10-16, the exact destination loaded a live Raise page promoting gifts and Raise Cash, rather than an error page. It did not, however, display a personalised code, the £10 amount, a currency, a minimum spend, an expiry date, a new-member rule, or referral-specific terms in the page content available for review. There is a material reason not to turn the directory label into a promise. Raise’s current public homepage says that, under its Referral Program, a $10 reward becomes available after the referred individual has made a qualifying purchase. It does not state on that page whether this statement applies to the newcomer, the referrer or both, nor does it give the qualification threshold or say that a UK-localised offer is £10. The exact link could open a country-, app- or account-specific offer that is only visible after installation or sign-in. The £10 Free record is therefore retained exactly as supplied, but the value, currency, recipient, qualifying action and availability require provider confirmation in the Raise app before a reader commits money. In practical terms, treat the link as a route to a possible current promotion, not as a voucher that automatically discounts every gift card. Do not enter a made-up code if there is no referral field. Do not make a purchase merely because a third-party page describes a different minimum spend or reward amount. The promotion may have changed, been targeted, stopped, or have additional rules. The safest evidence is the in-app referral screen and the checkout summary shown to the account that followed the exact link.

Shuffle Rewards
3 Months Free
Reward recorded in the directory: 3 Months Free. Use the exact referral code gzvc23 or the exact referral link https://shufflerewards.co.uk/. The reviewed official material does not state what “3 Months Free” covers or the campaign’s qualifying conditions, so readers must confirm the campaign terms with Shuffle before relying on it. Do not replace either stored value if the destination redirects, fails, or displays different wording.

Uber Eats
£10 FREE
Directory record: reward = £10 FREE. Referral code/link (preserve exactly): eats-swleslks55. Exact referral destination (preserve exactly): https://www.ubereats.com/. The destination was reachable when checked and displayed Uber Eats location/city navigation, while the site’s Great Britain promotions page describes invite-code promotions generally. However, the page did not display this exact code or a dedicated offer panel, so the £10 amount, who qualifies, any minimum spend, expiry, redemption mechanics and any geographic or account restrictions need confirmation from Uber at the point of sign-up. Do not treat the directory label as proof that the reward is cash, transferable money or a guaranteed discount on every basket. Uber’s own help says referral offers can vary by city and that offer terms may change. The exact code and URL above are retained unchanged even if the destination later redirects or the code is rejected.

£50 FREE
Recorded referral offer for TheFork: £50 FREE. Preserve and use the exact referral code E3B807EE and the exact referral destination https://www.thefork.co.uk/. The destination is the UK TheFork homepage. Publicly accessible pages confirm that TheFork provides restaurant search and booking, but they do not establish the referral offer’s qualifying event, recipient, credit form, fulfilment time, eligibility rules or exclusions. Provider confirmation is needed; do not assume the £50 is cash, Yums, a bill discount or guaranteed value.

Hilo
20% Off
**Recorded offer: 20% Off.** The live referral destination for this record displayed ‘20% off thanks to Zoe’ and invited a visitor to enter an email address to claim the discount and get started with Hilo. The exact referral code recorded for this promotion is **JACK TURNER**. The exact referral URL is **https://mention-me.com/m/ol/iv7esblc-jack-turner**. Keep both exactly as shown. For this particular referral, the link is the safest redemption route. The landing page uses an email-claim journey and, in the version checked, did not show a conventional box into which a visitor could independently type a code. Do not alter the URL, replace it with a search result, or assume that **JACK TURNER** will work as a general checkout voucher in a different Hilo journey. Open the exact link, enter the email address that will be used for the purchase, and follow the route it supplies. If the resulting checkout does not visibly apply the saving before payment, pause and ask Hilo to confirm eligibility rather than assuming it will be credited later. The live page specifically says that the refer-a-friend voucher and discount are valid for **Hilo devices only** and do **not** apply to accessories. It does not state a cash value, an expiry date, a device-by-device list, whether every subscription configuration qualifies, whether the percentage is calculated before or after other charges, or whether it reduces any recurring subscription fee. It also does not promise that the discount can be combined with another offer. Hilo’s terms say promotions may have extra conditions, are personal and may not be combined unless Hilo expressly says so. Provider confirmation is needed for all of those points at the time of purchase. Mention Me’s general referral terms add a material eligibility safeguard: a referred friend must not be a current customer and must never have been a customer of that merchant under any email address or alias; they must purchase after accessing the programme and meet any other stated criteria. Those are general platform terms, so the current Hilo programme terms and the claim journey remain decisive. The 20% is not cash, account credit, a refund of an earlier purchase, a discount on accessories, a waiver of delivery or return costs, or proof that an order will be accepted. It is a promotional discount subject to the live offer, checkout and merchant terms.

Oscar
£100
The directory record supplied for this entry records a £100 reward and the exact referral code/link A4DR6XOES, with the exact destination https://oscar.co.uk/referral. The code and URL are reproduced exactly and have not been shortened, substituted or altered. I could not verify how the code was meant to be applied, whether it was for a first purchase, a new customer, a particular product or a local franchise, whether the £100 was a cash payment, account credit, voucher, discount or another benefit, or whether a referrer, a new customer or both were intended to receive it. The exact referral destination did not return extractable referral content when checked, while the official homepage displays the cessation notice. Accordingly, the £100 is a recorded directory claim, not a currently confirmed entitlement. It should not be described as guaranteed cash, a reduction in the price of pet food, free delivery, a refund, insurance, credit, tax relief or compensation. The referral benefit is separate from the underlying pet-food purchase or local-franchise relationship: product prices, delivery charges, minimum orders, availability, substitutions, payment terms, cancellation or returns, data handling and any local eligibility conditions remain subject to the provider or franchise terms. Provider confirmation is needed before relying on any part of the offer.
