Globalization--LED Lamps

Ordered two LED lamps from Amazon along with some other things.  Specified free delivery as we weren't in any hurry for any of the items.  All but the lamps have arrived so I just checked Amazon to see where they were.  They're in transit from China with a 3-5 week travel time.  That amazes me, just seeing globalization and automation working in practice.  (Why it's more amazing to see an order delivered directly from China than the same order delivered from a warehouse in the US which originally came from China, I don't know.)
