Depends on contents and mode of delivery.If it contains a couple of ounces of illicit stuff, 10 days but youu2019d not get to read it for about 10 years.Delivery-wise, thereu2019s Air Mail - takes about 10 - 14 days average (thatu2019s what I found when I lived in Canada which uses same methods). Then thereu2019s surface mail - which used to go by ship, but more recently went by air as well when space was available. After a nasty incident whereby the UPS guy got frostbite while paddling between Newfoundland and Greenland, the US stopped surface mail. That leaves either Amazon drone or the sea slug route. Not sure how long they take.
