Sporttrade March Madness Promo Code
March Madness is here and our favorite betting exchange, Sporttrade, has a slam-dunk promo for new users looking to cash in on the action!
By signing up with our exclusive promo code SBOST, you can score up to $100 in withdrawable cash back - a game-changing offer from the top sports betting exchange in the U.S.
Once you've signed up, during your first seven days Sporttrade will track 3% of every bet you place. When the week is up, that 3% gets credited back to you as real, withdrawable cash - no strings attached.
That’s right—no turnover requirements, no hoops to jump through. While you’ll need to bet a solid amount to unlock the full $100, even smaller wagers will still earn you withdrawable cash - a rarity when it comes to sportsbook sign up bonuses.
