MLB Betting Promos: Claim $3,600 in Sportsbook Promos Monday
Let’s take a look at the best MLB betting promos today that you can use to bet on Monday, March 31 games.
bet365
| bet365 Promo | States Available | bet365 Bonus Code |
|---|---|---|
| $150 Bet-and-Get | AZ, CO, IA, IL, IN, KY, LA, NC, NJ, OH, TN, VA | TOPACTION |
| $1,000 First Bet Safety Net | AZ, CO, IA, IL, IN, KY, LA, NC, NJ, OH, TN, VA | TOPACTION |
| $150 Bet-and-Get + 50 Casino Spins | PA | TOPACTION |
Create a new sportsbook account with the bet365 bonus code TOPACTION in most states to get a choice between two MLB betting promos.
Your first option is a bet-and-get that requires a $5+ first bet in exchange for $150 in bonus bets win or lose. Alternatively, select a $1,000 First Bet Safety Net where you get back up to $1,000 in bonus bets if your first bet results in a loss.
For example, let’s say I pick the bet-and-get and place a $5 first bet on the Mets -1.5 (-110) vs. the Marlins:
- If the bet wins, I receive $4.54 in profit, my $5 stake back, and $150 in bonus bets.
- If the bet loses, I receive $150 in bonus bets.
