Meanwhile as a hobbyist I'd be glad for the discount "we will get around to it sometime in the next two weeks discount"
In Shenzhen you can have Some Guy in a truck doing a parts pickup round around town a couple of times a day. In the US you're waiting for overnight Fedex from Digikey. And sure, there's a lot you can stock in advance, but virtually every board will have this one weird part you don't stock yet.
Plus if you can get someone on the phone there can be value in that.
And if a sales engineer comes out and sees your operation you might get more than a free lunch…
