Anyone roll gift cards @ Publix to make your oop look higher?!

I've read about people doing this (or getting gift cards or whatever) but what a clever idea. When you are checking out and your total is next to zero or in the negative lol, you throw in a $25 giftcard to your order so it looks like you are paying $25 (when you are really paying zero) and keep rolling giftcards that way. The next time you shop you and your balance is zero (or +/-), throw in another $25 giftcard and pay for it with your 1st giftcard (so it looks like you are paying) and so on and so on! Thanks IpreferPublix!!!
