When I was at Stratford Upon Avon I noted there was much more variation amongst the bookies than I've seen before.
In one race an outsider was priced at 50/1 at one bookie and 150/1 at the bookie next door. Surely if you had a dongle and a box you could take advantage of these sort of variations on the exchanges? The average price on course would have been 66/1 so I'm assuming the lay price on the exchanges would have been there or thereabouts?
What do you think?
