I've got a complete set of Foersters Algebra, where do I sell it at?

[Prairie~Phlox]

My son is finished, Math w/o Borders disc too any suggestions on where to sell it & for how much, it's not cheap new.

Sell it in the classifieds on this web site. I price things such that they are a bit under what people are selling them for used on amazon, ebay or other book selling sites. I figure that I got my moneys worth out of them, so now somebody else can too.
