First off we realize that international shipping cost are very high. However, we do not profit from the cost of shipping as the rates are set by UPS and USPS. These rates are based on the volume of packages sent, and are set by the shipping companies. So high volume companies receive a more competitive shipping rate. Regarding shipping to places in the United States that are not part of the contiguous United States, shipping companies change 50-65% more to ship to these locations. This makes it impossible to offer free or $5 shipping when the cost of shipping to the location is substantially higher than shipping within the contiguous US.
I hope this answers some of your questions.
