My friends know that I am very much against the idea of store loyalty cards. If you haven't been to www.nocards.org, go there now and read.
But then there's reality and the fact that I can't really shop for groceries at a place that doesn't require one of these fake discount cards. Pretty soon you have a stack of customer loyalty cards in your wallet. I don't want to carry around a giant stack of these things all the time. Now there's a way out.
I heard of www.justoneclubcard.com today, which is more or less what I want. Now I need a printer.
