Ravens fans, are you feeling lucky?

If so, you might want to check out Saxon's Diamond Centers over the next week. The store, which has locations in Bel Air and Aberdeen, is offering a sweet-sounding deal on its jewelry; If the Ravens shut out the 49ers in the Super Bowl, all jewelry purchased between Jan. 26 and Feb. 2 is free (up to $5,000).

Sounds good, right? Well, here's the catch; there has never been a shutout in the Super Bowl. What's more, during their current three-game winning streak, the 49ers has scored at least 27 points in each game.

We've seen deals like these several times this year, with mixed results. An appliance store in Denver and a car dealership in Washington, D.C., offered full refunds on items purchased if the Broncos and Redskins were able to pull off a shutout. Both teams won, but neither blanked their opponent.

For those Ravens fans searching for hope, look no further than Alabama jeweler Jeff Dennis. Dennis made a similar gamble on the Iron Bowl between Auburn and Alabama, and he lost. But to be sure, the best college team in the country playing a 3-9 squad is much different than the two best teams in the NFL squaring off in the biggest game in sports.

(H/T to Game On!)
