Sorry to resurrect an old thread but wanted to chime in..

I LOVE my uPromise account. We put every penny we spend on it (and pay it off monthly) and do all of our shopping online via their turbosaver website. For example, Southwest Airlines had a deal this week for 10% back to uPromise plus another 2% if I used the uPromise credit card. So we bought tickets for our Florida vacation (which we would have bought anyway) and ended up with about $100 going into my son's 529 plan. Nice!

By doing this we routinely accumulate a few thousand dollars per year in his college fund buying things we would have bought regardless!
