Every day through Wednesday, September 28th, Domino's is giving away between 1,000 and 20,000 free Artisan Pizzas! Head over to their Facebook page, "like" them, and click on the New Artisan Pizza tab to enter. The pizza vouchers are being given out on a first-come first-serve basis at an unknown time each day. Follow Domino's on Twitter and be the first to know when the time comes!
Note that the entry page says that all pizzas have been given away for the day even when they have not. For all the details and to see how many free pizzas are given away each day, click here.
