Deposit 'x' amount in each account to recieve 'x' amount free bet.
then which website do i lay/back ? and i don't understand why i would lose 'x' amount in 1 account and gain in the other.
Yes pick any bookie to join plus you'll also need to join betfair as this is where you'll be placing your lay bets.
Deposit whatever amount the bookie says you need to eg £25 if your joining William Hill.
You back bet at the bookie and lay bet at betfair. Because these bets are exact opposites eg back Liverpool (to win) and lay Liverpool (to not win) you will always
win one bet and lose the other. You can't win both and thats the point. You win one and lose one so your cancel each of them out. For your first bet (back and lay) this is all your own money so by cancelling each other out you're making sure you can't lose (well a few pence is the usual "cost") but for this you've now "gambled" in the eyes on the bookie (they don't know about your lay bet at betfair) so now you've "qualified" for the free bet.
Now by doing the same back\lay again - but this time only the lay bet is your own money as the free bet is the bookies gift to you - you'll always lock in a profit
