Amazon’s Inverse Shipping Costs

What strange laws govern the economy of the parallel universe that is Amazon.com?

Okay, here’s one that boggles my mind. I ordered several unrelated items from Amazon on Sunday evening, part of which consisted of the following:

  • 2- Delonghi Oil Radiator Heaters weighing a total of 58 lbs. Free shipping (cost would have been $44.50) and delivered on Wednesday afternoon.
  • 2- Silver Cufflinks weighing a total of 4 oz. $4 for expedited shipping and delivered on Wednesday afternoon.
