I would suggest listing them on eBay. You decide the shipping amount. Look at similar listings to find out what other people are charging, or visit the USPS website to obtain a postage estimate. You also decide what types of payment you accept. If you will not be selling (or buying) often, skip the PayPal account and take a check or money order. Once you receive and deposit it, send the item right away.
