I can’t stress this often enough or loudly enough, always get a receipt! Make it habit, refuse to leave any store until you have one. Save them! I have a receipt for every purchase I’ve made going back 12-years. Of course you don’t have to keep them quite that long.

Never paying with cash is not the answer. If you are thinking of paying with cash is dangerous, just think what a unscrupulous clerk can do with your credit card. Many people have been ripped off in recent years by store and restaurant clerks who have borrowed their credit card.
