I don’t know how they do it with no shipping charge.
I have orders that have come on the same day from three different carriers!
I have been with Amazon for ten years and have had only three problems. 1) did not get a delivery. Upon notification they gave an immediate refund 2) a device quit working within a few days and they sent a replacement with packaging to return the bad unit 3) they make it so easy to order I am buying more then I should :-)
And you get more - Amazon Prime Video, Amazon Prime Music, Amazon Prime Books, Amazon Prime Wardrobe and Amazon Prime Pantry.
Anything you want, they make the hassle of you getting in your car and driving the mall to shop obsolete.
Whatever you order you get the next day and movies and books you get instantly!
The import coolie made goods and process it with unfedrpaid workers 1/3 of whom are on public assistance.
