Yes, it was $168 S.P but it's Lay price on the Exchange was $300.

In the same race No 4's S.P. price was $32 yet on the exchange it's Bet price was $36 and it's Lay price was $38...???

I've had a quick look at horses that are at least $30 on S.P. - it seems their Lay prices on the Exchange are higher than S.P.

This might suggest if one wants to Lay an outsider it could be better to do so on S.P. than on the exchange?
