I feel safer shopping with a credit card than cash because I'm only responsible for the first $50 plus my charges should the card be stolen or lost.
Other than the one credit card, I have NO debt.
CCards are good to use at times because of the lemon protection clauses in most agreements, but, pay it off if at all possible in 30-90 days like I do for durable good purchases. That’s about the only benefit I see.
