Chris’ advised prices are usually great value, Jimmy, but I would suggest that they often only shorten a little after posting (evening / night before the race), then frequently shorten significantly again during the day / before the off.
Look at the reviews, one of which Chris posted today, to get a feel of advised odds v sp. Then look at the historical figures to get a full overview of the outstanding service it is. Incidentally, Chris is kind enough to give us a heads up in here prior to posting.
