Glad you feel better....
Neither eBay or Canada Post can or will do anything for you. I've been in the import/export business for 30 years, it's always better to be on one side or another. Right now it's best to be an importer but we have had a long period, almost 10 years, where the opposite was true.
This is fact of life in international trade, you need to adapt or change your business model. Until oil prices crash or interst rates in the USA rise dramatically don't expect to see any weakening of the Canadian Dollar at least not vis-a-vis the US Dollar.
