"Day at Target"

So I was at Target the other day, you know the place...where you go in to buy 4 items and end up getting 20 and spending over $100...that place.  A mom and her daughter were arguing about a purchase...normally I agree with the kids because A.) We share the same mental capacity and B.) If it gets the kid to shut up, I'll do it...

Mom: "I'm not spending $5 on that!"

Kid: "It's NOT $5 it's $4.99!!!"

Mom: "It's the same thing."

Well Mom technically it's not the same thing...after taxes it would be $5.06...I was going to interject, but that wasn't my place.
