You could also try Etsy. It's an online store (not auction like Feebay) and they have *great* rates!
There's a minimal fee for listing items, items are listed for 30 (or 90??) days, you have your own *free* store front -- it's a great site. There's even a category for "supplies" which is probably where you'd list most of your items.
It's for independent crafters to have an online place to sell. The supplies dept would be a definite plus...lots of things sell on there, but crafters *always* need supplies! You could even discount your prices a bit since it's much less $$ than ebay.
Check it out. It's easy. No, I don't work for them, have no affiliation (other than as a buyer! yay!) but I am thinking about becoming a seller.....hmmmm
good luck!
