BetDSI Sportsbook is back with more promotions to start off your holiday season, and sports bettors aren't going to want to miss this opportunity for some free cash for the holidays! Diamond Sportsbook is offering up a 150% Bankroll Bonus to any of their current or new members.

It's a fantastic promotion for the casual bettor, as the bonus really could bump your bankroll quite a bit. All you have to do is make a minimum deposit of $300 and enter the promo code "Bet2012," in the promo code slot at the cashier's screen. What that earns you is a 100% sportsbook bonus and a 50% casino token that is available for the BetDSI Desktop Casino.

That's not all, though! You'll also get a free $50 bet that you can make on the Super Bowl as to whether the AFC or the NFC is going to end up winning the game. You just have to make sure that you email with the subject line "Superbet." In the email, you just need to provide your account number and which conference you think is going to win the game, and the bet will be placed for you.

The rollover on this bonus is 10 times, and the casino portion of the bet must be rolled over 40 times to be withdrawn. The minimum deposit is $300, and the maximum bonus is $500.

No matter whether you are a big time bettor, a small timer, or anything in the middle, you definitely aren't going to want to miss the newly announced $10,000 BCS Pick 'Em Contest! All you have to do is be one of the Top 100 point earners in this contest to win a cash prize, and the contest is totally free to enter. All you have to do is carry a minimum balance of $200 over the course of the previous 30 days prior to entering the contest, or you can make a minimum deposit of at least $200 to get free entry.

These two promotions can be joined together, and it's a great holiday gift to yourself. Just make a minimum deposit of $300, and you're all set to go to collect your 100% sportsbook bonus, your 50% casino bonus, your free $50 Super Bowl bet, and the free entry into the $10,000 giveaway in the BetDSI BCS Pick 'Em Contest.
