It would be extremely inconvenient for me if they actually required a signature for everything, especially since the UPS guy seems to hit my neighborhood between 11 and 2. But I wonder who you ordered from that you didn't at least have a tracking number to know when it's delivered.
I've noticed that
B&H and a few others are now requiring signatures for more expensive shipments, I had to drive over to the big UPS warehouse on I-45 to get my last lens shipped from
B&H becuase they wouldn't leave it on the doorstep. So now for the expensive packages I'll use FedEx since the warehouse is much closer to my home.
