Check That Receipt

I try very hard to pay attention during checkout, but I get distracted quit easily. HaHa It never seems to fail that when I do, I find a mistake on my receipt. Yesterday, I was having a great shopping day at Wal-Mart. My total was approximately $85 and after coupons should have been about $23, but instead came out to $29. Turns out the cashier forgot to scan 6 $1.00 off coupons. Always look your receipt over before you leave, and don't be afraid to speak up- politely, of course!
