There was no signature required for the shipment... UPS has been to my house a few times w/o any problems before [ ordering from Newegg before.] I contacted Crutchfield.. where I ordered from, and they put a trace on the package, and went ahead and shipped a second one.
[They also said to refuse the package if the 1st package shows up..which is doubtful, and I'm sure they are going to be filing with UPS for the insurance to pay for the second shipment.]
It appears UPS seems to be doing this quite often, based on this 'The Consumerist' article: »consumerist.com/2012/10/10/so-i- ··· y-house/
Edit: More information..
