So I suppose it wouldn't be a problem to have AFPW mentioned on Kaymount if AFPW's web site list kaymounts contact details..
Maybe they don't want to take the chance.. Kaymount is the worlds largest distributor of weather balloons, so I'm sure they make a nice commission from AFPW.. If a large order were to come directly to AFPW via kaymounts websites.. AFPW just may take the offer, leaving Kaymount "the middle man" without a profit.
