Napa Valley Grille

SoCal eats. Check your local eateries and beer houses for giveaways. In Los Angeles, for instance, Angelenos have until March 20th to "like" Napa Valley Grille Westwood and/or Cafe del Rey and submit their bracket to win a party for six ($300 value), $100 in dining cards, or an all-expense-paid trip to Vegas for the perfect bracket. (Did we mention the quintillion stuff?)

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!
