Exactly. I wouldn't get the card for the debt, I would get it for the rewards and tracking. And even though I plan not to have any debt on the card, I'm not signing up for a 24% APR, when I can get better benefits elsewhere for 13%.
This doesn't make any sense.
If you don't plan to keep any debt on the card (meaning you pay off the balance on time every month), then the APR is irrelevant. It doesn't matter if the APR is 24% or 13% or 80%, it won't affect you. You're not "getting better benefits" because of a lower APR.
