I had to send a package by priority Express which guarantees 1- day shipping in MOST destination in the US. East coast, for example, will not be delivered if you drop off your package at 4pm cut off time. To ship a package to NY the next day, I had to do a bunch of researches and make numerous phone calls. Each branch seems to run on a different schedule than other branches, so it's wise to call ahead and make sure.As far as cut off times, from talking to an associate at Lynden post office, it didn't sound like next day shipping to NY is available, but if I found out, I will update. At Mt. Baker station, cut off time for next day shipping to NY, according to the associate there, is 11 AM. At downtown Bellingham location on Magnolia ST is 12 PM. If someone desperately needed to send it off next day, and the truck left, and you are willing to drive, Marysville post office near Premium outlet would be 2:45PM truck leaving at 3PM.As far as pricing, Fedex or UPS, you are looking at about 100 dollars for my own (not USPS) large box about 4lbs with 14 by 15 by 5. (more or less depending on arrival time..) With USPS, it's about 51 dollars, but if you pay and print at USPS.COM, it's only about 37 dollars, so it's less than half the price. None can beat that price.Lastly, Lynden post office has always answered the phone, (even on Saturday) answer all your questions, are really informational. And if you create an account online, you can order shipping supplies free of charge; the come to your door within 3-4 business days. USPS is the best!One note on Saturday shipping, although Lynden post office is closed on Tuesday, you can still bring a prepaid package before 12PM and it will go out on Saturday; saves you a drive to Bellingham!
