Used books no one wants

It took Sean McCarthy from Popmatters seven years to sell his copy of REM’s Monster to a used record store because a ton of people bought it and then half that ton tried to sell the damn thing back. I asked one of our used book buyers what the Seattle used book equivalent was. Care to try to guess what title every person with a box of books tries to sell to us? An envelope full of galleys to anyone who can nail it before I update this post with the answer at 7pm Eastern Pacific Standard Time. ANSWER (guessed by Lance and Jack at pretty much the same time): SEABISCUIT.
