You guys don't read the terms. It's not about whether or not you have great credit to qualify for the 0% APR in the first place, it's the fact that these programs are to get people who can't even pay their bills on time to suffer even more. The loan installment is thru your credit card.
Good, let the people who can't pay their bill suffer. Their interest pays for my cashback. I pay my bills on time and benefit for it. Why wouldn't I take advantage of a 0% APR loan on a phone if it exists?
