Meh, I've been doing it all of 4 days so I know nothing. But if you're placing other bets as well I'd have thought you'd be ok. I'm placing bets on the Copa and on other Euro games so that it looks like I'm just betting and happen to be using the offers (you'd be mad not to??). Today I've got a bet on all three games. One is the free £5 from yesterday, one is £20 on the special and one is £10 on the other game with a loss of 35p! Today worked out nice as the MBS will only cost me 83p if Sweden don't score. Yesterdays Poland game was about £1.50.
Will probably be gubbed tomorow!
I put the Coral one in to Yesbets and it showed as you said, not sure how I mark that bet on yesbets it if the lay wins though. I know I'll get a free bet and make the profit, its just how to account for THIS one on there.
