Pizza Hut

Pies in the sky. Sign up at Pizza Hut's program, and you'll get yourself an email coupon for a free medium one-topping pizza if all four No. 1 seeds make Atlanta — something that Pizza Hut itself concedes has only happened once, back in 2008. And, if the four make it to the April 6-8 tournament, you gotta hustle: The coupon's redeemable through April 15.

Best March Madness deals, giveaways

Your odds of randomly landing on a perfect March Madness bracket? Rounded down, roughly 9 quintillion. Quintillion — that's one billion billions. As one betting site put it, "If every person on the planet were to fill out 10 MILLION brackets each, the odds are less than 1% that even one of them would have a perfect bracket."

Comfortingly, your odds as an informed insider drop down to 128 billion to 1. So you might as well enter your perfect bracket in as many contests as possible. For those who don't want to be bothered with nailing 63, check out these more forgiving giveaways. -- By Vera Chan, Yahoo!
