I've once returned Amazon via each UPS and Kohl's
Kohl's was definitely smoother and quicker. It was an item that would have cost more to ship than it was worth. But I don't think I had a choice which shipper to use.

"There is a cult of ignorance in the United States, and there has always been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that "my ignorance is just as good as your knowledge."
-- Isaac Asimov
