I only ship my bows internationally, but I also found that Canada tends to have a lower shipping cost than everywhere else. I have a price for Canada, a price for Mexico, and a price for everywhere else. If you look on USPS, they have a chart of zones. I think there is 3 for international shipping, and it is really helpful. I would put the information in your shipping policies. I would also let them know that shipping times really can vary quite a bit for international shipping, so they will need to be patient.
