Do you have some post-holiday shopping you've been wanting to do for yourself? If so, Chase just announced a great new promotion for Chase Freedom cardholders to kick off 2012. When you shop at Amazon.com from 1/1/12 through 3/31/12, you can earn 5% cash back on up to $1,500 in purchases. That's $75 cash back, which is really a great deal for a credit card with no annual fee.
