What happens if you get into some monthly thingy, where you have to pay like 2 dollars the month?Yeah, why don't you guys get a debit card? works just like credit but you can only use the money you put in the card. That way there is no overbuying. It's what I use.
I was lucky enough to find a debit card that have 0 monthly fees. I mean OMG how awesome is that? I bet that if you guys look around you might find one company like that also.
