Knebworth House - discount vouchers?

Mumto2

Does anyone know of any discount vouchers to get into Knebworth House (just the grounds - dinosaur trail etc).

I'm sure I saw something last year, but it's not in my Days Out voucher book this time.

Thanks:j

There's 2 for 1 in here but it's only valid Monday-Fridays excluding bank holidays. http://www.letsgoeastofengland.com/

Or a similar voucher with the same restrictions can be found in those free mags you get in libraries like Primary Times.
