They are the worst (well UPS Mail Innovations is as bad-- they both add many days to shipping and make the service massively worse).
Nine days. Nine! UPS Ground gets here from there in about 4-5 days, USPS will ship a 2lb 6x6x6" box from here to there Priority in 2 days for well under the shipping charged. Fedex Ground says 2 days from here to Indianapolis, I just checked.
Heaven forbid if a SmartPost package gets lost or damaged, because everyone will point fingers at everyone else and claim it wasn’t their fault. BTDT.
