Um. Crap.
So I have declared it 'sell all the assigned books from spring term that I don't feel the need to keep' day. Also 'get rid of all the Marion Zimmer Bradley and donate the proceeds (plus the original approximate sum spent on the MZB, counting shipping) to RAINN' day. Tra la la go to Amazon find book go to put book on Amazon Marketplace OH WAIT AMAZON.
Where, other than Amazon Marketplace, do y'all sell your used books?
