See the pictures here of how Amazon.com is going to cause a long and painful death for Walmart and other Brick and Mortar businesses.

I have not seen these pictures before of an Amazons.com's "Product Fulfillment Center".  Fancy name for gigantic warehouses around the country that serve a particular geographic area. 

It seems this should be something Wal-Mart fears long-term. 

Technological change advancement, peoples willingness to use that technology, and new patterns of buying behavior will serve to accelerate "creative destruction" in the retail sector.
