I done some business on ebay selling off my old books and also bought some weaving supplies and yarn through them.  You might try it with a few things and see how it goes.  If you've got a lot you may want to consider an ebay store.  You have to be patient with ebay though, I've found a lot of stuff doesn't sell the first time around but when I relist it 9 times out of 10 it sells.  All in all it's a pretty easy way to do business and move merchandise.

good luck !
