Q: Where can I redeem American Express Platinum Card Points online? I think I’ve accumulated a lot and I want to cash them in!

A: You’ll earn one reward point for every dollar that you charge with the American Express Platinum Card. And once you’ve earned enough points, you can redeem these points to pay for everything from airline travel, hotel stays and high-end electronics to restaurant gift certificates and home office products.

Redeeming these points is easy. You simply have to log onto American Express’ Membership Rewards Program homepage. Once you do this, you can shop in any of several categories, and you can then redeem your accrued points to pay for travel, merchandise or gift cards.

American Express is known for some of its more unusual rewards offerings. For instance, with 3,500 points you can pay for a one-day snowboard rental at Copper Mountain Resort. For 2,400 points, you can purchase a plaque filled with used dirt from a Boston Red Sox game.

The Membership Rewards online mall is a fun place to shop. Just make sure to keep earning those points; window shopping isn’t nearly as much fun as is placing an order for Farmville game cards.
