Whaaaaa! Here's a site I just came across today:
http://www.buydvd.com/books.asp The prices look excellent even though the selection could be wider. I'm going to try ordering from them to check out their shipping and speed and so on.
EDIT:
www.dollarmanga.com has cheap Comics One stuff, like Iron Wok Jan and Now! Unfortunately their shipping is atrocious: $29 for a $50 order? Unacceptable!
I'm just going to wait till they have a sale.
EDIT2: For those who were wondering, buydvd had excellent service and dollarmanga still has outrageous shipping prices.
