Do you have _______ doujinshi?
For the most part what you see is what you get although I have a number of doujinshi that are not up for sale. Still, there is nothing wrong with asking.
Are the doujinshi you are selling new or used?
All of these doujinshi are second, third, or fourth hand. Unless there is something wrong with them though (loose pages, folding, etc) I make no notes of their description.
What forms of payment do you accept?
Check or money order is preferred. In a pinch I will accept paypal but I prefeer not to and it can only be used in some instances (contact for more information).
