Places to sell a h-manga

I duplicated a purchase of a /ss/ manga off of amazon.co.jp anyone know where I can sell it?  I dont think I can sell it on ebay cause of its content.

Selling it on eBay should be fine.

I dont think it is (granted its not actual cp dont think its worth the risk on that one) and I cant use paypal on mature items anyway so I think that option is out.  Anyone got any other ideas?

I just relized you can return things to amazon.co.jp but what I read couldnt be right:
Return handling fee applied for all products. For CD, DVD, Software, Game, VHS, Electronics, Home & Kitchen items or Toys & Hobbies, you will receive only 15% of item's price.

Although it doesnt say books I have no idea how much Id get back anyone got ideas?
