OTOH, I don't think i've ever had an amazon delivery person deliver one of my packages a couple houses down. That has happened to me a couple times with both UPS and fedex (although one must be specific with fedex when it comes to normal fedex or fedex ground).

The last time it happened it was a Christmas gift and I didn't even know about it until the person it was delivered to IM'ed my wife using one of the neighborhood contact services. Turns out the delivery company even knew they delivered it to the wrong address because they put "delivered to XYZ instead of ZYX" in the delivery notes.
