Understanding the Wal-Mart Effect

From Tech Central Station:

"I'm writing this column in West Virginia, USA having just come back from shopping in Wal-Mart, the extraordinarily successful supermarket chain that makes our own look slow and tiny -- not to mention expensive! I had to keep blinking at the price labels. With my notion of prices tied to British expectations, Wal-Mart's just look as though the staff can't do their sums."
