Four carriers.
One list. Cheapest first.
You do not have to guess which carrier is cheapest for a package — enter it once and every service from all four prices itself in front of you. This page is for when you want to know why.
The cheapest option for most parcels under about five pounds, and the only carrier that delivers to every US address including PO boxes.
Strong on heavier parcels and guaranteed delivery dates, with the most reliable tracking detail of any carrier.
The strongest choice for time-definite air freight, with sharp economy pricing on lightweight residential parcels.
The fastest option out of the United States, with customs clearance handled end to end.
Which carrier usually wins.
Useful for planning. Never a substitute for an actual quote, because zone, dimensions and surcharges move the answer.
