Bury have offered free entry to all fans for their rearranged League Two game against Southend on 21 April.
The original fixture on Saturday was abandoned after just six minutes after torrential rain left the pitch at the JD Stadium unplayable.
The Shakers had asked fans who had been at that game to collect a voucher for the rearranged game, but have now opened it up to all supporters.
Bury have said it could cost them up to £9,000 to stage the rescheduled game.
Before the original game, heavy rain leaving left puddles on the surface but referee Tony Harrington opted to start the match.
Following further downpours, the players were called off the pitch and when it was clear that the surface would remain unplayable, the game was called off.
