The most lucrative charge card we've found is the GM card that allows you to earn money toward a new car. You get 5% of your purchases on the card put in an account toward the purchase of a new car. We've bought three cars using these points and have saved around $6000 on those cars with the card.

We also have the Disney Visa (1%), Marriott Visa (3% on Marriott purchases and 1% on everything else), and a Cash Back rewards card (1%). We take turns using these cards depending on our needs.
