We just got back from our local Wal Mart. I picked about a $120 worth of close out stuff in the hunting section. Once I had checked out my wife ask me if I had checked my reciept to be sure I only paid what the actual cost was. I hum hawed around aroung and finally said "NO". She checked my reciept and they had overcharged me $9.65. Once we got the money backI ask her if she always did that. Of course she answered. She went on to tell me that at christmas she found a $60 mistake. She used to work at Wally World and she says sometimes the mark downs don't get entered into the registers for a couple of days. Now I am wondering how much I have lost by not checking the reciept. Us being retiredwe have to be careful with our money.
