I once told a rather officious person [here in Bexhill] that a book on sale was very overpriced-this was quite a few years ago! He was a jobsworth who would never budge on anything and insisted that the prices were set by an "expert" dealer. I said that we used to have such an establishment in town. If the Charity Shop was now a Book Dealership, they should be prepared to negotiate [as per the previous business that always did] and that the clue was in the name. He wasn't very compliant
I bet the book was pulped.
