Those saving for college and shopping for Christmas can take advantage of Bank of America's Upromise World MasterCard, which gives cardholders 11% cash back when they shop online at Upromise.com through Dec. 31. Those reward dollars go straight into a designated college savings account set up through Upromise and Sallie Mae. There's also no annual fee.
Read the fine print: The introductory rate of 0% only lasts for seven months, after that the variable rate ranges from 12.99% to 20.99%.
