More than seven million customers have used the app since launch and have earned over £200m in their Cashpots, which they can use to reduce their grocery bills. The £15m Spin the Wheel bonus is the single biggest giveaway since Asda Rewards launched 12 months ago. Depending on where the wheel lands, 50p, £1, £5 or £100 will be added to their Cashpots. To win their share of the £15m up for grabs, customers need to spend £5 or more in-store or online, scan their Rewards app and spin the wheel. The supermarket has launched a new ‘Spin the Wheel’ game in its Rewards app giving customers a guaranteed Cashpot bonus every time they ‘spin’ during September. Asda has today announced it will give away £15m to customers throughout September to mark the first birthday of its hugely popular Asda Rewards loyalty app.
