Think of this as a spin-off to the "DVD Bargains" thread. This thread is devoted to any kind of comedy purchase, whether it be a DVD/video/audio/book etc. which you think is of interest.
To kick things off, I've just found this in a branch of "Aged UK" this morning: Dad's Army - The Defence of a Front Line English Village. It is a book chronicling some of the stories from the series, supposedly written by Arthur Wilson M.A., nephew of Sergeant Wilson. Marked originally at £6.99, I got it for £2.99. One thing I've already learned from it - Walmington-on-Sea is in Sussex.
