I'm looking to buy namco clamshell (hard plastic) famicom cases in bulk for my games. Any cheap case is fine so long as it's the same size as standard nintendo famicom boxes, but so far the cheapest choice seems to be all of the family stadium and other sports titles released by namco. Here is a picture of what I'm talking about.

I don't mind buying individual ones, just as long as shipping is reasonable. (that's why I figure buying in bulk would cut shipping costs down, especially if it's coming from japan)
