It’s really easy to use. Once you have your card and register with their website you search what shop you want to use and if they’re affiliated it will give you a discount code or you just produce it in a shop and they’re affiliated they knock the money off. I’ve literally saved loads this month as Asda and Morrison’s are giving 10% off. When I applied for mine in 2018 it was £5 for 5 years. I immediately made my £5 back with my discount taking my kids to Nando’s.
