i've never going to learn all the grocery codes.... impossible. i suck at numbers. when someone gives me change, i hate the people that give me 12 cents to get back a quarter. my mom does that all the time, and i can never figure out that math in my head. i wish i was better in math. its always been my worse subject, ever since 2nd grade and i was the only one in my class that didn't understand long division (and those invisible pull down numbers).
