Mainly betfair isnt a bookies ie its done online but instead of changing odds with bookies you do it with other people who are also logged on...advantages to that is that you tend to get better odds with betfair than you would with a bookie. Plus you have more markets to bet on and unlike a bookie where you place your bet and thats it...with betfair you can bet whilst the game is being played so you can change your bets at any time ie if you back a team to win and they arent then you could always back the other team or back the draw if its going that way.
Ok thanks for explaining this I'll take a look at this sounds interesting also there offering new members a Free £25 bet.
I'm looking to bet on
Uruguay to Win
Spain to win
Brazil/Holland and German / Argies I'm struggling to call may put Brazil to qualify instead of winning.
