I live in Canada and getting items from people who use this program isn't cheap on our pocket books. I much prefer to get items from people who don't use it. Duties and such are a cash grab.....period. And that added section for duties is (censored)! 99% of the time I don't dinged for duties when it goes via the post office. UPS or any of the other companies....watch out....They will nail you with brokerage fees and such. I know all out this. I am a courier and see it happen all the time. I guess if a person is doing high volumes and such....this is a good thing to use. But if you are small time seller.....Take the time and do your patrons a favor and not use it.
