From BBC News story today: e-books were one of the consumer goods added to the "basket" of goods tracked to compute inflation in the UK.

DVRs, hot chocolate, white rum, blueberries, and chacuterie were also added. Champagne, sink faucets, and something called a freeview box were dropped.
So, sit back sipping on rum-laced hot chocolate reading your e-book while your DVR records the TV. I'm not sure how to work in the processed meat & blueberries.
