bet365's Cash Out features offers you an ever updating "cash out" price while your bet is in play. At any point, you can accept that cash out offer, take the money and run!
The cash out ability is offered on a wide range of bets and markets (although not all of them), and constantly updates as live odds change, when goals are scored, etc.
If you think one of your teams is lucky to be leading, see them get a man sent off, or simply think your cash out offer is too much money to turn down, you just need to click on the offer to settle the bet then and there!
