Just discovered this app and reward scheme. A few friends have reported good results of £50 and £60 with it and MSE have a article on it so happy it’s legit.
Basically you link your phone number, debit cards you spend on and it’s automatically gives you cash back when you shop at retailers. When you’ve reached £10 you can swap it in for credit against your phone bill.
I am planning on using it to buy Asda gift cards ( instant e vouchers) prior to weekly shop and get 4% back into the pot.
To locate the gift cards you click bottom right. “More” and want to earn more rewards.
Worth a try, and you can often use with other cash back sites /blue light discount.
Heres my referral code if you want it. 87AVD3NM
