Beware UPS: from a guy in my building:
Okay, Ladies and Gents, it's time to give you a heads up on UPS.
UPS has been having some major theft problems. For a brief period I was asked to use them to send my optical goods out to a certain optical lab. A few weeks ago, three of my packages were either stolen or lost after they were deposited in a UPS box in downtown San Francisco. They were never found and I had to foot the bill for some of the contents' worth.
I mentioned this to my UPS carrier and he told me that they had to fire a large number of workers in New York City due to theft. It's apparently a well kept secret.
In general, home delivery doesn't require a signature EXCEPT if you place a monetary value on the goods you are sending. If you list nothing, they are liable for only $100 and can leave the packages at the property, but I have heard of packages being left at the wrong address several times so the packages may indeed have been delivered. . .but not to us!
If you put a monetary value on the package, the MUST get a signature. It costs a little more, but it is worth it these days.
If you have a choice of carrier, my choice is FedEx. I've never had a package lost with them. Locally, OnTrac is also good as is Norcal.
