I wonder if it's just easier to put an absrud price is rather than bothere to do the research and then gradually reduce the price over time if no-one buys it?
This was the one I had in mind in particular; https://www.abebooks.co.uk/servlet/BookDetailsPL?bi=7274215549&cm_sp=det-_-bsk-_-bdp .. Just interested in the signature mainly, though thing is I'm not so bothered about it as I would have been a few years ago. But surely if the bookseller had priced it more reasonably, or reduced the price over time, then they could have sold it (I would have paid 50 quid for example) and then re-invested that money in another book to sell for profit, rather than just having it gather dust on the shelf :s
