Already had a couple of >30/1 winners on Betfair, glad I signed up. It's weird the way they calculate their odds, I just looked for tomorrow:
Ward/Jorginho bookings on 365 are 4/1 and 11/4 respectively. On a bet calculator, that's 17.75/1. 365 offers 18/1 on a bet builder.
Betfair prices are actually worse, 7/2 and 13/5, which equals 15/1, but the Betfair price for the double is massively better, at 23/1.
