I just sat down and looked over my receipt from my grocery shopping trip today. I had both kids with me and apparently wasn't paying as much attention as I should have. I usually review my receipt before I even leave the store and if there is a mistake, which happens a lot, I stop at customer service on the way out. Even if the error isn't in my favor, I'll tell the store. But only if I catch it before I've left.
On my receipt from my shopping trip this morning, I just noticed I was only charged for 2 of my 12 pks of pop. I saw the guy come around with the scanner and scan them so I just assumed he got them all.
I also noticed that the conditioner I bought didn't ring up at sale price. So I was overcharged for 2 bottles of conditioner. The over charge was only about 64 cents though.
This just goes to show that it is so important to review receipts before leaving the store, even if the kids are with me.
