I've learned my lesson...

I'm always going to look at my receipt from a store before I leave the parking lot! Since I have become a coupon shopper sometimes I go to more than one store to get the good deals. Well, today I went to four stores, which really didn't take too much time since I was only getting a couple of things, and for some reason when I came home I decided to check a receipt to see if they gave me credit for something. What I was looking for ended up being right but I noticed that they didn't give me credit for something else. That is what made me think I should check my other receipts. On another store they didn't give me credit for two coupons that I actually gave the cashier! How strange is that? I'm hoping just a simple error since the store is at no loss to me using a coupon. So, out of four stores two got it wrong! I think I will be checking my receipts from now on!!
