Well, they’re definitely reputable if that’s your concern, Fergie. As someone has already pointed out they’re one of the biggest bookies in the UK and that kind of branding goes a long way when trying to entice online gamblers. I promote the sportsbook and make a few quid with them but have never tried the online casino.
If you have UK traffic already, it can’t hurt to give ’em a try if they’re offering you a decent revenue share. And you can promote them via UK PPC such as Espotting and Overture UK and even Mirago.
