I have to assume that you are "speculating" that you will actually be able to buy 25 of these chips when they are released. Just to play devil's advocate; what if you can't? In the future you might want to think twice about listing something on ebay that you don't actually have in your hands.

It doesn't really matter though, because your price is double what 95% of the regular chip dealers and New Issue Services are charging so I don't think you will be selling many of them. Best of luck to you.
