Dealing with place betting is particularly tricky. Had a similar query to PP regarding place bets.

Created an account with Dynamic RaceOdds on a trial basis and was looking at the place markets yesterday.

Looking at the results from yesterday on the price at the jump - Betfair V Sportsbet it's probably a 60/40 win to Betfair as to who has the best prices for the place.

Not forgetting the fact you may have received even better odds during betting.

BUT the one issue is the relatively small pools. If you look at pools for R2 MV.
Victab is holding 206.5k while Betfair is 19.4 so it certainly wouldn't take much to struggle to get a bet on. Especially if you weren't betting on a metro meet on a Saturday.

Centrebet also looks to offer fixed odds place betting on Sat metro markets [at least].
