I am having a problem with the pricing for US and International Shipping.

The store is located in Canada and shipping prices are reasonable for domestic shipping. When I test shipping to the US or Internationally, the prices are outrageous. They also don't seem to be altered by adding additional items to be shipped. For shipping of a single item, the problem seems to correct itself when "ship in own box" is selected. Of course, this would not be a workable solution.

Another poster was having the same problem with their USPS Shipping Module: http://www.zen-cart.com/forum/showthread.php?t=39991

I am not sure what to do. I am using Zen Cart Version 1.3.0.1. I am not sure that upgrading will fix this problem.

Not sure what to do....
