Yes, can definitely see something like this happening. This is an area where PB hasn't had much room for manouvre in terms maximising revenue - I'd suggest the 1901ers might want to lube up in a year or so's time.
I think we'll have a real go next season as the 1901 memberships are up for renewal at the end of the season. The ideal scenario would be if we are looking good for automatic promotion and they can hike the prices up (40% minimum I'd guess)
