Do TopSport ever have promos?

Not the kind that we would use in the plays.

They do have $2 lines on some sports, which can be useful for finding middles. However, the main benefit of a TopSport account is that they are good for dutching and for arbitrage.

They have good odds, and they are happy to take large bets.

They also have a loyalty program which awards points for deposits made and bets placed. You can then redeem those points for bonus bets.
