That is soemthing that happened to me recently when Adorama sent me the Sigma 35/1.42 via UPS. I checked the internet and it said that it was delivered at the porch, but I saw nothing. Thanks God he ha hidden it between couple of bushes. Either way, it is unaccetable. FedEx always requires signature for those items. That is something ADORAMA (hint, if they are reading!!) should change. Require signature from the addressee, especially for an $899 lens, and if possible change UPS for Fedex, or even better and cheaper, the US Post Office. The same day, I receive via Fedex a hood for the 85/1.8 that I puchased form an OP here. I had to sign for the $20 hood. Good for him.
A signature is required for most UPS shipments upon receipt. Someone must be at the address to receive the package and sign for it. Packages cannot be rerouted or picked up from UPS. If you require additional help to receive your package, please contact us.
Unfortunately, some UPS delivery men seem to be as easy to control as a bunch of 5-year olds in an ice-cream factory.....
