Fair enough.

If you've never bet it sounds more difficult than it is. Would recommend at least reading that Student article and the Guardian one though. It's not even gambling. The crux is that every bookie has a variant of 'bet x amount and we give you a free x amount bet'. All you're doing is placing a bet for one outcome (example, England to win) and betting against that outcome with Betfair (England to draw/lose) to qualify for that free bet, then repeating the process with the free bet. Withdraw money, it's that simple.

Only issue is you can only do this with each bookie once and they are strict about this.
