Same here, and i am so relieved it is coming before Christmas! I already told my soon to be brother in law that it might not make it in time. Christmas is saved!
Not sure - the USPS site says the label was created on 12/13, was accepted in Phoenix on 12/19 and that it is Priority Mail; nothing to indicate the shipping method was changed/upgraded.
Huh...my notice (via UPS My Choice) only contains a valid UPS tracking #...didn't get any USPS notifications...though I haven't gotten many from USPS anyway...I think it may have to do with how they have the zipcode as the 9 digit hyphenated one...
