Ive just registered with William Hill to put a bet on E/w and it says I get a free £10 matched bet (obviously I know I need to put £10 on to get this)
I want to put an each way bet on (£20 total stake) but it wont let me use the free bet as the other half of the e/w.
Its says The free bet cannot be used to place bet(s) on the same market(s) or event(s) as your qualifying bet(s).
Does that mean I can't do it?
yep in short you cant do this. you'll have to place it on a single of some sort and you'll probably find that you have to put it on a bet with odds greater than evens.
stops people from signing up, betting on united to win, and on united not to win to meet the wagering requirement, then withdrawing their free bet risk free.
