I wish they did net profit per game. It kind of sucks to take a team and the over/under, win one of each and still have to pay commission. Still the best service out there, I shouldn't complain so much.
No SS, its on profit only.
Lets say you are in a live wager, you put put $100 on team A at +110, then later you can lock down a $100 wager on team B at +130 and team B wins, All you pay is commision on the $30 bucks, and not the $130, and you pay no comish on the losing wager at all.
