I have a somewhat stupid question... so my first book is available on Amazon, and I was surprised to note recently that there are now two used copies for sale (so somebody actually bought it?!) and now there are even four. Now, never mind that one of them is about 20 GBP more expensive than buying the book new from Amazon direct (could be one of my two signed copies, though that would be very strange ). What I've noticed is that all four "used" copies are being sold by what look like bookshops, and they all have in their product description "new, print on demand" instead of "used". So... I don't get it. Are they selling used books or are they just offering the same new print-on-demand book that Amazon itself is offering? Anybody know? BTW - confirmed sales so far are exactly one, and that's a friend of mine. I haven't looked at the sales statistics from the publisher yet, I am under the impression they don't come out until a few more days from now.
