MAD
Once again SODS LAW at work ....theres only fifty cents difference in the win and the lay price of both Sunderland and Villa .Its unusual at that price but there you go .
In my own defence most bookies will have the outsider at say11.00 while Betfair will have them longer as in this instance about $16 so if your LAYING your still risking paying the bigger odds (thats where Gamebookers P2P may be better for laying the outsider )
