If you're interested in flying in two months to Buenos Aires, you may not be able to find a free ticket. But neither do you have to settle for the first fare quoted you. Bide your time. The closer it gets to the date of departure, the more eager the courier service will be to make a deal. The only red tape involved is an application form that the courier service will ask you to fill out.
Some services also charge minimal annual registration fees.
The reason for couriers More and more businesses are using courier services. The reasons are simple. First, nearly all major businesses now operate internationally. If packages or documents are shipped by traditional methods, they can take hours, even days to clear customs. Not so with material shipped with a courier.
