A few notes to used booksellers

If you can't sell hardcovers you're charging too much.  I've picked up a lot of stuff that I never would have bought before because it was only a few bucks.  Then it's off your shelves.  It's all well and good to only want titles that quickly move but it limits the possibility for large sales.  If I'm interested in the genre I already have some of the key texts.  However if I just found a new author I want everything not just their major award winning books.
