Are you a member of Upromise? I am, but unfortunately don’t do a lot with it. :(
Upromise is a free service that helps you get money for college bills and student loans from the things you do all the time: buy groceries, shop online, fill your gas tank and much more.
Certain brands that you buy earn you money in your upromise account. And at certain places that you shop – CVS, Publix, etc.
You can find out more and sign up here.
