I have been using Shopmium recently. Shopmium is an app that gives you cashback (some up to 100%, most are at least 50%) off products at supermarkets. The app is very easy to use and they are no additional charges for cashback money. I have set up my account to send money back to my PayPal.
if you use my referral link you get a FREE can of Pringles. Just download the Shopmium app and enter my referral code is2u7m 😊 www.shopmium.com/uk/referral/is2u7m
My recent goodies using this app have been Nutella wafer bars and costa frappes!
