Woburn do have reciprocals with other clubs, which can be used to access guest rates(£50 iirc).
They also have specials on from time to time(I assume when they have days that are really quiet), like this £189 for breakfast, 18 holes, 2 course lunch then another 18 holes on some days in May:-

Which I would consider a good price for food and 36 holes at that venue and I do love the courses there.
I saw that deal and was tempted by it
