BUT, you have to be good with money or you will get in over your head (what they are hoping) and end up with credit card debt at 15%+ interest.
People like me that can afford to pay off my credit cards in full each month can make out like a bandit on these deals. But people with no financial discipline and the inability to pay off the debt the rack up before the higher interest kicks in are the very dupes these deals are created to con.
Sounds like you’re doing it right!
