Epic WTF

I used to work for a second hand bookseller listing their stock on Amazon. That kind of thing is pretty common. You get a bunch of fucking amateurs out there who find a book that no-one else has in a certain condition or edition etc. and because they don't have a clue how much it is worth - and because they're either unscrupulous or a bit dim or both - they whack it on there at a massively optimistic price. You then get similarly clueless people who use that price as a baseline and then try to undercut it by a few quid. Morons, basically.
