A family member told me about airtime rewards before Christmas and I think it is definitely worth spreading the word.
it is an app where you sign up with your mobile number (if you are on a contract) and can connect your bank card(s). Any spending you do at any of the registered shops (wilko, boots, greggs, argos, hundreds of places both high street and online) you earn a percentage back. You can then cash in and get the money off your phone bill. I have made £68.31 since getting it. You can also do challenges where you do for example 5 x £1 spends and earn extra money off that way but otherwise it just runs in the background.
just thought worth sharing...you can get £1 free with my code
