Yes, VS just reminded me of something I've heard many times "no"; how many times have you called a businesses to buy something they advertise for sale and they tell you flatly "no"? Or "we never get those in"? Not "those are out of stock at the moment, but we'll have more on X, let me put that on backorder for you". Why would and business print a catalog each year full of things they can't/won't sell to you?
I've also encountered various procedures surrounding getting things the don't have: they once took down my name and phone number then called me over a year later to say the parts I asked for are in stock, did I want to buy them? Another time they asked for my credit card which they would charge when they shipped, but could not say when or if that would happen.
It all comes bact to inventory control; I'm not sure what the arrangement is, but I get the idea EAA doesn't have any say in what parts they receive nor when.
