【移英慳錢必備】超市買餸即買即賺！JamDoughnut 現金回贈 App 教學 (+ 專屬推薦碼)

在英國生活，每星期去超市買餸絕對是一筆固定的開支。除了登記各大超市的會員卡（如 Nectar、Tesco Clubcard）儲分之外，其實還有一個可以「賺雙重回贈」的秘密武器 —— JamDoughnut。

有別於傳統要等幾個月才批核的回贈網，JamDoughnut 主打 「即買、即用、即刻回贈」。今日就為大家拆解這個移英港人手機必備的慳錢 App！

1. 什麼是 JamDoughnut？運作原理是什麼？

簡單來說，JamDoughnut 是一個買 電子禮品卡 (Gift Card / e-Voucher) 的 App。當您透過這個 App 購買各大商戶的禮品卡時，它會即時回贈一定比例的現金積分（通常介乎 2% 到 10% 不等）。

實際操作場景：

您在 Asda 或 Sainsbury's 買完餸，推住架車去到收銀台，見到總數是 £50。
您即刻打開 JamDoughnut，用銀行戶口或 Apple Pay 買一張 £50 的超市禮品卡。
App 會即時彈出一個 Barcode（條碼）。
您將這個 Barcode 掃入收銀機當作付款，交易完成！
同一秒，您的 JamDoughnut 戶口已經賺了大概 £1.50 至 £2.00 的回贈積分。

2. JamDoughnut 的三大優勢

點解咁多人用？因為它完美解決了傳統現金回贈網的痛點：

即時入帳： 買完禮品卡的一瞬間，積分已經存入戶口，不用等幾個月。
雙重回贈 (Double Dipping)： 您依然可以掃描自己的超市會員卡賺分，然後用 JamDoughnut 的禮品卡結帳，一次消費賺兩次著數！
涵蓋商戶極廣： 除了超市 (Asda, Sainsbury's, Morrisons, M&S, Aldi 等)，還包括 Primark, Argos, B&M, Costa Coffee, 甚至 Uber Eats 和 Deliveroo。

3. 如何註冊及領取迎新獎勵？

JamDoughnut 的兌換率是 100 積分 = £1。當您儲滿 1,000 積分 (即 £10) 時，就可以直接 Cash out 將現金轉入您的英國銀行戶口。

🎁 輸入推薦碼，互惠互利！

下載 App 後，在註冊時輸入本站的專屬推薦碼：NAZG

當您成功儲夠 £10 並完成第一次 Cash out (提取現金) 時，系統不僅會將您的現金轉入戶口，本站也會獲得 £5 的推薦獎勵。這能大大支持我們繼續為大家開發像 Costxx 查貨助手這樣的實用工具！通常新用戶首次購買禮品卡時，App 也會派發額外的迎新積分。

4. 實用小貼士：不要預先買太多

雖然回贈很吸引，但建議大家 「買幾多、入幾多」。最理想的做法是：進入超市時攞定手提掃瞄器，或在收銀機「do」完所有貨品，得知確切的總金額後，才在 App 內輸入剛剛好的銀碼購買禮品卡。這樣就不怕禮品卡內有餘額忘記使用，真正做到零風險慳錢。

總結

小數怕長計，每星期去超市買餸慳 £2，一年下來就慳了超過 £100！立刻下載 JamDoughnut，輸入推薦碼 NAZG，配合我們的 Costxx 工具，做個最精明的移英消費者啦！

[Essential Money-Saving Guide] Buy and Earn Instantly at the Supermarket! JamDoughnut Cashback App Guide (+ Exclusive Referral Code)

Living in the UK, weekly supermarket grocery shopping is an absolute fixed expense. Besides registering for major supermarket loyalty cards (like Nectar or Tesco Clubcard) to earn points, there is actually a secret weapon to earn "double cashback" — JamDoughnut.

Unlike traditional cashback websites where you have to wait months for approval, JamDoughnut focuses on "buy instantly, use instantly, get cashback instantly." Today, we're breaking down this essential money-saving app that every UK resident should have on their phone!

1. What is JamDoughnut? How Does it Work?

Simply put, JamDoughnut is an app for buying Gift Cards / e-Vouchers. When you use this app to purchase gift cards for major retailers, it instantly rewards you with a percentage of cashback points (usually ranging from 2% to 10%).

Actual Usage Scenario:

You finish your grocery shopping at Asda or Sainsbury's, push your trolley to the till, and see the total is £50.
You immediately open JamDoughnut and use your bank account or Apple Pay to buy a £50 supermarket gift card.
The App instantly generates a barcode.
You scan this barcode at the till as payment, and the transaction is complete!
In that exact same second, your JamDoughnut account has already earned about £1.50 to £2.00 in cashback points.

2. Three Major Advantages of JamDoughnut

Why do so many people use it? Because it perfectly solves the pain points of traditional cashback websites:

Instant Credit: The moment you buy the gift card, the points are deposited into your account. No waiting for months.
Double Dipping: You can still scan your own supermarket loyalty card to earn points, and then use the JamDoughnut gift card to pay. One purchase, two rewards!
Wide Retailer Coverage: Besides supermarkets (Asda, Sainsbury's, Morrisons, M&S, Aldi, etc.), it also includes Primark, Argos, B&M, Costa Coffee, and even Uber Eats and Deliveroo.

3. How to Register and Claim Your Welcome Bonus?

JamDoughnut's exchange rate is 100 Points = £1. Once you accumulate 1,000 points (i.e., £10), you can cash out directly and transfer the money to your UK bank account.

🎁 Enter the Referral Code for Mutual Benefits!

After downloading the app, enter our exclusive referral code during registration: NAZG

When you successfully save up £10 and complete your first cash out, the system will not only transfer your cash to your account, but our site will also receive a £5 referral reward. This greatly supports us in continuing to develop useful tools for everyone, like the Costxx Stock Tracker! Usually, when new users buy a gift card for the first time, the App will also issue extra welcome points.

4. Practical Tip: Don't Buy Too Much in Advance

Although the cashback is tempting, we recommend "buy exactly what you need." The ideal approach is: pick up a handheld scanner when you enter the supermarket, or wait until all your items have been scanned at the till. Once you know the exact total amount, enter that precise figure into the App to buy the gift card. This way, you don't have to worry about leaving unused balances on the gift card, achieving truly risk-free savings.

Conclusion

Little drops make the mighty ocean. Saving £2 every week on groceries means you save over £100 a year! Download JamDoughnut right now, enter the referral code NAZG, pair it with our Costxx tools, and become the smartest consumer in the UK!
