If you go to http://www.nfl.com/sweepstakes/gmc
and enter to win the Superbowl tickets and GMC vehicle. Sign up with e-mail address, select options on GMC vehicle you like, and enter ame and address info, then a popup will come up giving you a unique GMC code for a test drive worth $50! Write down or print out the code and follow instructions for test drive and redemption. Gift card options are GMC's discretion but are listed on GMCTestDRive50.com. I do not know if this is national or targeted, so YMMV.
