Amazon has extended its controversial patent on "1-Click" shopping to include items bought as gifts for others.
The original 1999 patent allowed customers to purchase products with just one click after entering their address and credit card details for upfront storage. but drew fire including a boycott when Amazon sued rival Barnes & Noble for using a similar method.
One lost book, one disgruntled customer and a potential million dollar legal fee for Amazon - it's the latest in a series of morality tales showing how e-commerce companies can be hit where it hurts most due to bad customer experience.
