More than a week later, the drop still hasn't arrived. I've very cross right now regarding this. UPS blames USPS, USPS blames UPS, and Massdrop, well, they don't have a good explanation other than what the tracking already tells me :| The problem ultimately sits with Massdrop using UPS SurePost, which is guaranteed to be the slowest transport possible. My second drop got here within three days because it was purely with USPS.
Massdrop, please learn from this. No UPS SurePost to Alaska. Use USPS only when shipping to the Last Frontier, that way it doesn't get stuck somewhere :(
