oldbloke's mutterings

The Mansion exchange now has 0 fee for buyers, and only 1% for sellers.
They don't run anything like as many markets as some other exchanges, though.
Let's check some odds... BetFair in brackets...
1.90 Juventus 1.97 (1.92/1.93)
3.69 Draw 3.88 (4.5/4.6)
4.46 Arsenal 4.71 (3.8/3.85)

mmmmm, the disparity in the draw & arsenal figures means they might be worth checking when looking for arbs.
Other than that, the gap between the buy & sell looks worse at Mansion. But that's just one data point. And the 0 commision makes a difference.
Next time I fancy some sports betting, I'll probably check what prices they have.
