IT has been tracked around Federal Way for 5 days. This package started out with UPS on the 3rd of February, then UPS dropped it off at the Post Office.
No worries, I am going neither Far nor Fast. We love USPS Flat Rate Boxes here in Alaska, it's the only way to go if it will fit. I rarely do business with anyone if they will not ship USPS.
UPS and Fedex will take your money for any service you want, next day no problem - only thing is there is no next day delivery here in Fairbanks.
