Fellow Strayan, completely agree. How hard would it be to have it calculate shipping a screen earlier, given (Mass)Drop has my country/address attached to my account?
Maybe then they could add a "We ain't shipping this to your country" message to the item. Or let you exclude items you can't actually order.
It's surely not terribly-difficult to implement and would add a lot of functionality, as well as reducing a LOT of frustration as an international buyer.
