Apples vs Organges
That's the difference between Door to Door and Airport to Airport.
77c a pound will get you to destination airport, you have to add to this the departure and arrival airport handling charges, various fuel & security surcharges then go queue and collect your freight. If the arriving freight is from a non US origin point add your customs clearance charges on top.
FedEx & UPS collect it at origin and deliver to your door for an all inclusive rate...
