Watch Your Cashier

I was going over my receipt from Wal-Mart this week and realized that the cashier did not correctly price match a few of my items. Instead of .88 per lb she put .98 per lb. I realize that it doesn't appear to be much, but it adds up when you're stockpiling. So, my bill should have been about $5 less!! I normally try to keep track of exactly what they are putting in, but I couldn't see it on the screen. I really don't think she meant to, but if I would have caught it I could have saved myself some money! Lesson for the day: watch your cashier (or the screen)!
