1. Bullcrap!.... It's a bit much to expect small companies, with constantly changing stocks to be able to instantly update their internet stock. (And, with Chamber's machining facilities, I wouldn't have been surprised if they hadn't said to you they could run a couple off soon for you.) you'll have people believing that Midways carry all the stock they advertise, next!
2. Maybe people don't like talking to you??! Biggest issues in this world could easily be solved with good communication.
3. Buying the screws, even at Chamber's prices, would certainly be cheaper than paying a Master craftman's rate!
