Your bookie and betfair accounts are completely separate so naturally any winnings will be withdrawn back to your bank (or whatever deposit method you chose-debit card is probably best).
You'll see from this it's better to try and win at betfair and lose at the bookie as it saves you the hassle of withdrawing, your money is in betfair where you want it, the bookie doesn't lose and will see you as "profitable" and are thus more likely to offer you repeat free bets in the future. How do you lose at the bookie. Go for the higher odds option is the obvious suggestion but there are no guarantees....
Deposit bonuses are just that. You make a deposit and you automatically get the bonus-no need for a qualifying bet. The downside to a deposit bonus are the terms / wagering requirements.
You'll understand by now that for most bets you lose a little bit of profit each time you bet. So if for example you've got a £50 bonus for depositing £50 eg you've now got £100 in your account BUT the WR is 5x the bonus amount eg £250 before you can withdraw, you can see that there is potentially a lot of betting to do before you complete the WR.
Ideally then you want to bust out at your first attempt eg bet the full £100 in your account and lay it off at betfair in the usual way but with the hope that you lose the bookie bet so all your money and the bonus is transferred into betfair.
If you happen to win the bookie bet then you can't withdraw your cash otherwise you'll forfeit the bonus so, what to do?
Your next bet should either be for the full amount in your account again, or if this amount is now more than the wagering requirements (you might now have in excess of £200 in your bookie account) then just bet up to whatever amount will meet your remaining WR.
Either way you're working your way to meet the WR (remember the min odds terms of the offer as any bets placed under these odds won't count towards the WR) or you'll bust out as intended. Usually every bet you subsequently make shaves a little off your potential profit so there is a technique known as underlaying where you sacrifice a bit of your anticipated profit (should you bust out in one) in favour of gaining a bit from the bet should it win at the bookie (instead of losing a bit as described above). By doing this if you win the bookie bet then you made a little bit extra to compensate for having to complete the WR - if you managed to bust out then you've sacrificed a bit of profit.
Underlaying when the odds are above 6 is the best way but if you dont see why this should be the case then it's probably too early to consider doing yet. Whilst underlaying isn't particularly complicated I wouldn't recommend it for the beginner. Get a feel for the system by completing the free bets before you go on to the deposit bonuses would be my suggestion.
