Mar 22 and Mar 29, YouBet offers no-vig Pick3's at Sam Houston
 

I don't know if this has been posted already, but it's a very nice deal.

From YouBet:

Here's how it works:
1. Play any Pick 3 at Sam Houston on Monday, March 15, 22 & 29.
2. For every Pick 3 ticket you cash on Youbet.com, you will earn a Winner's Bonus equal to 13.64% of your gross Pick 3 winnings for the day - effectively eliminating the 12% track takeout for the Pick 3 at Sam Houston.
3. Pick 3 bonuses will be credited by the Wednesday following each Monday program at Sam Houston.

In the fine print there is a $1K max on the amount of the bonuses for any account. That still leaves room for a $7300 payoff.

I have been thrilled with their 10% rebate on gross earnings for the Tampa Bay Downs weekend Pick 4's.
