About Jam Doughnut

JamDoughnut is the original instant cashback app that lets you earn money back when purchasing giftcards for major supermarkets and retailers. Buy giftcards through the app at face value, receive instant cashback, then scan the giftcards at the till to pay for your shopping as normal. The platform covers almost all UK supermarkets and many popular retail brands, making it easy to save money on everyday purchases you'd make anyway.

Sign Up Bonus Details

New JamDoughnut users receive a £3 bonus when they sign up using my referral code (GMN2) and purchase their first giftcard through the app. The bonus is credited to your account after your first giftcard purchase is completed.

To use the app, simply buy giftcards for your favourite supermarkets or retailers through JamDoughnut at face value, then scan them at the till when shopping in-store. You'll earn instant cashback on each giftcard purchase, with rates varying by retailer. The cashback accumulates in your JamDoughnut account.

You can withdraw your cashback once you've accumulated £10, or alternatively you can swap your cashback balance for another giftcard if you prefer. Compare cashback rates across different supermarkets using Scrimpr's supermarket cashback comparison tool to maximise your savings. UK only.

Bonus amount: £3

Refer a Friend Bonus

JamDoughnut operates a refer-a-friend program where both you and your friend receive a cash bonus when they sign up using your referral code and make their first giftcard purchase. The exact bonus amount varies but is typically around £3 for both parties.

You can find your unique referral code in the JamDoughnut app settings. When your friend uses your code and completes their first giftcard purchase, you'll both receive the bonus credited to your accounts. There's no published limit on how many friends you can refer, making it a good way to build up extra cashback alongside your regular giftcard purchases.

Referrer reward: £5

Referee reward: £3
