One shopper managed to cut their Asda food bill from £52 to £12 after taking advantage of the supermarket's "hidden" price labels.
The Asda regular told YorkshireLive they were an "Asda Rewards" member and made the £40 saving by keeping an eye out for Asda Rewards labels in their local store.
The app works by encouraging shoppers to target certain products to get money back into the app which they can then convert into vouchers to spend in-store.
