This has been an interesting discussion! I have on more than one occasion had Fed Ex and UPS declare that they delivered something when, in fact, they had not. This occurred on days I was home, and had been in the front part of the house working, and would have heard the truck. One showed up a couple of hours after I canned the carrier. One was re-sent my the merchant - no issues. There is definitely an issue in my neighborhood with package theft. On more than one occasion, cars have been observed following the delivery trucks. Yuck!
