Although you can generate some extra income by using cash back credit cards (and making sure to pay off your balance in full every month), I recently discovered a website where it actually pays to save money rather than spend it: SaveUp.
SaveUp is a free tool that links directly to your bank account. Every time you either save money or pay down debt, the site issues credits which can be used toward opportunities to win cash and other prizes. Additionally, the site features a section that offers tips and advice on all things financial.
