I already used my reward and lost the ticket, serves me right when playing conference league qualifications.

Cash is always better than free bets, you can withdraw it immediately or if you use it to bet like I do you get the stake back with the winnings. When you use free bets you don't get your stake back, meaning you have to hit one game with odds @2.0 just to convert it to cash. I know it should be obvious but stating it here anyway since I realized recently that a lot of people doesn't understand the difference.
