I have just read through the postings on matched betting and find it more confusing that it should be.There is no need for any complicated laying at Betfair to release Free Bets as a very simple alternative is to just back both sides of an event in a 2 event outcome.
For example in the Football Markets there is The Total Number of Goals in the Game Market-either Odd or Even-only two possible results as 0-0 is classed as Evens.
William Hills Telephone Offer is Bet £30 and get a £60 Free Bet.
Corals Telephone Offer is Bet £30 and get a £60 Free Bet.
In the first game you back an Odd number of goals at Hills with £30 at 10/11 and you back an Even number of goals at Corals also at 10/11 with your £30.
When that match is finished you withdraw £57 back to your account(£3 Loss) but £120 Worth of Free Bets.
The following day when your Free Bets are available repeat the Bets in the next match using your Free Bets-the Odds are exactly the same.Whatever the result you will be able to withdraw £54 from the winning account(stake is not returned) giving you a profit of £51 Guaranteed.
Next day you move on to another two bookmakers.
Send me a PM and i will happily send you comprehensive instructions including the relevant promotional codes.
I have a list of over 50 major bookmakers to use.
