Okay, first time posting, read the forums and really like this place. Not sure if this is the right place, but recently while at the gas station I saw that you could get like visa gift cards? or something along those lines? Could those be used to purchase stuff online? (don't have a credit card of my own, and no way rents would let me use theirs) If so do you put them in just like a normal credit card? & What are some good online trusted & safe sites that I could order from?
