The award for best sports betting promotion ever goes to Mansion, who have set up this little gem for the start of the NFL season.
Place a bet of $1100 on Pittsburgh to beat Miami on Thursday and they will refund your stake if you don't win.
You can't bet less than $1100, and if you bet any more the maximum refund is still $1100. And you have to back the Steelers. But if you can bankroll this bet a, it has a huge risk free return. The bet you have to make is a point spread handicap at -110, therefore paying $1000 for the $1100 wager. That's a free shot at a grand. Or, as I've done, you can hedge it (as long as you use a different site) and lock in nearly $500 profit guaranteed!
The point spread was actually zero when I placed the bet, so I backed PIT with $1100 to win $1000 and then hedged betting MIA using their promotional -107 line at CanBet, risking $535 to win $500. Except really there's no risk:
If PIT win, I win $1000 and lose $535, net profit $465.
If MIA win, I win $500 but do not lose on the other bet.
So I guess I'll be cheering for Miami on Thursday, to try to win the extra $35. That's about as much as I'd normally put on a game...!
