Why not both? There's no downside to using a card, cash back, extra warranty on some items, less hassel. Just pay it automatically each month. Right now I'm paid $150 a month for using a card.Why in the world do you need credit when you have money to buy things?
All a credit score tells you is that you have debt or had debt recently. I would much rather have 3 million in the bank with no debt than have 800 credit score.
