Basically that's a bit of a shame, as if you don't have an account yet you can sign up via an affiliate that gives you cashback on your commission payments. I've got a BetFair X account through The Gambling TImes and every month I get a payment to my Skrill account just for using BetFair in the way I would've anyway. Not sure there are any other people that offer this service, but even if there were I'm not sure I'd trust them in the way I do TGT who have never missed a payment, and I can in fact verifiy what I'm expecting and what I receive and it always tallys.
So are you in that rare, but wonderful, position of needing to set up a new BetFair account? Then read about the BetFair Cashback scheme before you do it.
Value betting is all about the small margins you can take advantage of, and this is one of the best. It's a no brainer really.
