Thanks for posting the link... now this is all cleared up 

USPS is barely competent. When they deliver packages to me, they stick them underneath my stairs on top of my neighbors grill (neighbor stores his grill underneath my stairs). The first time they did this, I thought the package hadn't been delivered and the merchant sent a new one. I literally found the original package two months later. Now I have to remember to check under my stairs daily when I'm expecting a package. I still forget sometimes. A few months ago a 5970 sat on top of the grill for at least 24 hours before I realized it was there.
