Send a bag from Costa Rica to Quito(Ecuador)

hi  all!

anybody knows how can I send a bag from Costa Rica(San jose preferably) to Quito(ecuador) or if not to bogota? Is there any secure and not very expensive way?

Thanx a lot in advance!

DHL is a carrier out of Costa Rica.

You can use the Post Office and pay extra for their  'tracking service', similar to registered mail. With the tracking number the PO can track it...but the individual can't.
FEDEX is another choice.
