If I ever put a bet on it is always in the old fashioned way at the bookmakers, so i wouldn't have the option of cashing in..
You can still cash out those bets mate, you just have to ask them how much they want to pay you to take it off your hands.
Yeah with big singles they'll give you a cash out exchange. I'd love to be in the position to even contemplate this but these sort of bets always seem more of a gamble than standard footy bets, it's nothing but a wild punt and I'm not that type of gambler.
