When trying to decide on pricing books I took Cristo's advice and looked at Bookfinder. All you have to do is type in the ISBN and lo and behold it's all there.

I've just checked out the prices of my AGA cookbook and AGA weekend cookbook and find that they are priced from £27 - £198. Why the discrepancy? They all seem to have the same ISBN, all published 1996 and 1998 respectively. I then tried ABE and they have them from £30 to £95. They both have cheaper EX-library copies. I just don't understand why anyone would want to pay £198 for a cookbook or are they just dreaming.
