I just purchased a Legacy slim wallet (not the one with the turn lock). I am really trying to minimize what I haul around with me each day. The card star app is great, I have been using it for some time now. So now I have this very sleek, elegant wallet that fits into my small bags.
There is also an app called coupon Sherpa so you don't have to carry coupons. I never had my coupons with me when I needed them. I always forget the app but probably cos I wasn't in habit of using coupons cos they were never with me.
For those who don't have a phone that gets apps you can often just give your name or phone number & SA can look up your loyalty card number.
