Lol. No, none that I'm aware of. Ebay and other main-stream online auction sites have a rule that all clothing must be clean, to keep out the used panty/stocking/sock selling. Can't have kink ruining their sites!!!
I would suggest that you send them in a plastic bag for a couple of reasons. First you want them to arrive still, ah, 'fresh'... But you also don't want the possibility of the scent to cause something to happen to them in transit either.
Never know when you'll get a postal inspector with a really good nose, or a mailman who just happens to have their own panty fetish.
