just keep in mind the more hands that touch them in the process the more the cost goes up. I would suggest setting up some form of order form - that way you only buy what you need so you don't have a mountain of them sitting someplace with someones money wrapped up in them. Simply order them quarterly or the like and distribute then. Or see if the manufacturer can make them available on a website or something. As some of us want them I don't see them being in significant demand once the initial wave comes thru (just my opinion).
Just for the record - I have still not seen anyone list what they cost. I would like one as long as the cost is reasonable. I don't mind if someone makes a little bit for their involvement in the ordering and distributing either - it takes time and I would not expect someone to do it for free.
