Each carrier has a speciality that they focus on. Some are cheaper on mail, some on packages, some on large packages, etc. Some companies don`t ship to all countries. We ship worldwide and for large and very large items DHL does a good job for me at the lowest rates I can find~ and they include the insurance. But, this is only for BIG items and only to some destinations. For smaller items, UPS has good rates but again, only to certain destinations and only certain sizes and packaging. USPS also provides reasonable rates for mail and the small stuff going to other countries and they`ve been dependable as well. It can cost a fortune to ship to certain countries or territories, no matter the size, weight, packaging or carrier. Each has to be considered to determine the most cost effective method. Once you`ve tried the services and shipped many items to many places all over the world you`ll have a better idea of who does what better and at the best rate.
