This is an excellent usefull tool.
In the case you are traveling back home from Aruba with too many luggage or items you bought here on the island and you are affraid of the high charges you'll have to pay on overweight luggage or too many luggages, here's also a solution or alternative:

Amerijet Cargo Airline has a special service called SPS (Small Package Service). Their services going out of Aruba include Miami, New York, Caribbean, Central & South America.

Of what I understood was that they have the main office at the Airport Cargo Building, but they also have an office downtown at the floor under Cooks Restaurant. I saw it their while visiting Cooks Restaurant and then I went back for inquiries on their services the next day. Because sometimes we buy a little more than what is permitted on the airline going back and therefore were paying a hefty price for it.
