one of my favorite things to do while grocery shopping is wait until all our items have been scanned, and then give the checker our savings card so we can watch as the total drops. it like a slot machine. you're not sure how much you're going to end up with. so, last night we went grocery shopping and went through the self check-out. we rang everything up and then scanned our membership card. we ended up saving $29.06! the bill was cut almost in half. i thought i was going to pee my pants.
