L.A. Times journalist David Streitfeld has discovered a mysterious phenomenon at the megalith on-line bookseller Amazon.com. His report: "On Nov. 6, seeking to boost my dubious culinary skills, I decided to buy "The Cast Iron Skillet Cookbook." I went to Amazon and placed the book in my electronic shopping cart but got distracted and never finished the transaction.
The next day, I signed on to Amazon again. A pop-up message informed me that the price had increased from $11.02 to $11.53."
Application of the economic theory of dynamic pricing? " "Prices change," Amazon.com spokesman Sean Sundwall said. "Prices go up, prices go down."
