At the moment, according to oddschecker, ALL BAR the following (which you can probably guess!) are paying 5 places:
Tote
Betfred
Ladbrokes
Hills
(There's no indication in Coral's column but they never offer 5 places)
One or two might offer six places tomorrow.
I'd like to add a question of my own...
At what time does the best price guarantee usually kick in?
Boyles paid 6 places last year
