By downloading the app onto your smart phone and signing up to Asda’s rewards app for the first time, users receive £5 which is deposited in their digital wallet inside the app, known as a ‘Cashpot’.

The money can be spent in store or online and there is no minimum spend required. The offer ends on 28 February.

By shopping in Asda, app users collect cashback in their Cashpot. To spend your cash you must convert it into a voucher which is then deducted from your shopping bills. Vouchers can be credited from £1 to £100.

Last month, Asda extended the period customers have to spend a voucher once it has been converted from cash, from one month to three months.

Unused cash in a Cashpot that has not been converted into a voucher expires six months after the month the cash credit was generated.
