Frequent Shopper Card Tip

I just added another frequent shopper card to my keychain the other day and counted them up. 20. That's normal right, for a person who mainly shops at yardsales and thrift stores? Two are library key cards (one for myself and one is Jacob's). So really, it's only 18. How many frequent shopper cards do you have on your keychain? (Yes, there is 20 on my keychain, you just can't see them all in the photo).

Here's a tip on protecting your shopper cards - put a piece of clear tape over the UPC code - that will prevent the UPC code from wearing away.
