1. Find a voucher mission
Vouchers are only available on the app. Go to the Missions page and select a voucher mission — for example, the "£1 off natural yogurt" mission requires you to bank two yogurt pots to earn the voucher (T&Cs apply).
2. Claim your reward
Once you've completed the mission, tap the claim button, then go to the Rewards page to find your voucher. It can take a minute or two to appear - refresh a few times if it doesn't show up right away.
3. View your voucher
Tap the orange block, then tap "Claim" on the pop-up to open your voucher. Here you can review the T&Cs and check how much time you have left to redeem it.
4. Know the time limits
You have 14 days from the moment you tap "Claim" to use the voucher in store.
Once you activate the voucher, you only have 20 minutes to use it — so don't activate it until you're at the till.
5. Redeem in store
When you're ready to pay, select your store:
Sainsbury's, ASDA, or Waitrose: Select the store, then verify your product by taking a photo of its barcode (you'll need to allow camera access). Once verified, you'll be asked whether to share your location — either choice is fine. Your voucher will then be ready. At the till, select "Giftcard" and scan your voucher on the bottom reader.
Tesco: Select the Tesco button and choose whether to share your location (either is fine). Your voucher will appear. At the till, select "Coupon" on screen and scan your voucher on the bottom reader to apply the discount.
6. Need help?
If you run into any issues, ask a member of staff at the till - they'll be able to assist.
