bet365 offer on city/barca game deposit £100 place pre match £50 bet on goals under 3.5, returns £70 place in-play £50 bet on goals over 3.5, returns £137 obviously only 1 bet can win but if 2nd bet loses its refunded and not as a free bet either, it can be withdrawn. you can play about with different odds to either win a couple of quid or win a couple of hundred, current odds on over/under 1.5 goals can net either £10 or £170 win remember to put the worst odds bet on 1st
I've got away with it too but just pointing out they reserve the right to do sumert about it. You never know.
