I sell just about anything on ebay that i can make at least $10 profit on. I bought a box of books for $1 one time ... sold ONE BOOK for $800.
wow $800 was that book made of gold or somethign what was so special about it? tell me what book it was so that I can see if I have one just laying around here boy if i found it that baby would be gone lol.
Whatever doesn't sell (or things that you think you might get more money from) you could always sell it on eBay.
