The "never use CC's, EVER!" rule is another one people will take a hard line with. It's popped up more than a few times right here in ATOT.
This one baffles me too. I mean, I get that some people just are incapable of using credit cards without running them to the max and then wondering why their estimated payoff is measured in decades. But for someone that can maintain a zero balance and play the multiple-card rewards game, the rewards can be pretty sizeable.
Last year with just two cards, my wife and I had ~$600 in cash back. This year so far in rewards and signup bonuses (we added 2 cards), we're already close to $1k cash value, significantly more than that if we redeem them for airline tickets (as we're planning to for a wedding we're attending in the spring) by transferring 1:1 to Southwest or United.
Haven't paid a cent of interest in years, and have gotten $3k+ back in the last 3-4 years. But nope, you should never use credit cards.
