In reply to jamestr:
I sold them from Craigslist to a Marine who drove up from Cherry Point. I had them listed for a while before somebody bit, and mine were perfect and had all of the center caps. The market for those is fairly slim- a lot of people want to run larger rims than 15", it seems to be the hardcore performance guys who want them for the weight savings and the cheaper tires.
Just be patient, somebody will take them sooner or later. If you want to sell them quickly, post on the nearby lists as well: Greensboro, Winston, Eastern, etc. If you want to ship, throw them on Ebay, too.
