I don't understand how people part with their money so easily. Ebay and Paypal do nothing. You list the item, you pay to have it listed, you answer questions about it, you pay a final value fee, and if you use PayPal (which happens to belong to ebay) you pay a percentage of the total value to them. Ebay discourages giving a discount to those who use methods other than PayPal.
At least someone who works on consignment is doing the sales work for you.
