I've offered them for a while and had about one sale a year, but I charge more than usual and don't emphasise it on my site. You could probably sell more if you pushed it, but I wouldn't expect it to be a major thing. The sales section on AW is worth a look too.

I used to do this before I escorted. I never got many sales through AW, www.ebare.co.uk was much better - just had a quick look at it now and it's changed a lot since I last used it, but there are still used knicker sales on there. There's also a site www.usedpantyportal.com which I used to go on, it has a forum used by sellers and panty fetishists, a very interesting read!

The problem I had was receiving payment, PayPal and most others don't allow adult sales, so you'd need to be very careful. I had a P.O. box for a while so I could accept cheques and postal orders, but you do need to give your home address and this can be found out quite easily. AW has the advantage that you'll be paid in credits, though they take a cut. There are topics on here about taking deposits from clients, I think the same methods could be used for worn underwear sales.

I never made a great deal from it, but it was good fun and not too much effort
