Twice in the last few months I've had a package change status to "delivered" -- while I was home, and suspiciously just a few minutes before 5pm. One of them was never delivered. The other one showed up 2 or 3 days later... I'm losing faith in those 2-day guarantees, and the number of items available for Prime has been slowly dwindling. That, and their minimum spend for certain items went from $25 to $35. Starting to wonder whether renewing my Prime membership is actually a good idea.
