I found this wholesaler last night and I just wanted to share it.

They're a wholesaler from China and they're dirt cheap. They even have Hello Kitty, Nightmare before Christmas and a few other things you can think of. They ship various ways including UPS, FEDEX and other international shipments. UPS seems to be the cheapest to receive shipments with.

You can find various cosplay items and even character bags not found on other sites here, as well as some hentai-ish items like the mouse pads with boob cushions (I always found those to be fascinating XD)

If you don't feel comfortable with that, you can always try: Animewild.com or http://www.399animeshop.com/ I've bought from them, they ship from Singapore but their prices aren't that bad either.
