I recently made a small order from Lawson Equipment (free shipping). I got a confirmation of my order quickly, and, although I never received notice that the order shipped, within a few weeks, the item arrived.
People are different -- maybe for smaller orders, he doesn't routinely send "Your Order has Shipped" emails. To me, the important thing was that I received the correct item within a reasonable time. Is he the industry's top leader in client communication? Probably not, but I wouldn't hesitate to buy from him again just because he didn't send me a shipping email. YMMV.
