As a public school teacher, I know that new textbook editions come out all the time and I have found that there are surpluses in the bookroom. Maybe if you befriend a v.p. or do a bartering (volunteer) for a current/used textbook, that might work!
I would try your local friends of the library and see when they are going to have thier next sale. Also our school district sells thier used textbooks so I would see when thier next sale is. Our school district also sells desks and tables and even used stand alone chalk boards.
Try http://www.vegsource.com/homeschool this is where we buy and sell used books and supplies. I've also had some luck with library book sales and the local homeschool fairs and conventions.
This takes a bit of leg work but I frequently see homeschool books at garage sales. In fact, one sale I went to last summer must have had 200 books for quite cheap, a dollar or so a book.
