Page 2 of the thread and 2 up from the bottom they state how they got them to work.

He has a budget of GB£10 per month for his online Ladbrokes account and if he loses all that he is SOL until next month.  That said he hasn't had to top the account up for 3 months so all those 50p bets are doing the trick.................lol.  I have no legs to stand on if we got into the "wasting money" chat, I daren't actually add up how much I spent on Poser Content alone last year let alone other bits and bobs blush
