Cookies can be very expensive

The Checkout blog today spotlights a bizarre practise I wouldn't have imagined existed: Marketers are using your cookies to play with price points for flexibly priced goods (magazine subscriptions, airline tickets, etc.)

Basically, the post explains how clearing your cookie cache can change the prices you're shown at online storefronts. Offering different shoppers different prices is a longstanding marketing tactic, but this is an impressively personalized level of targeting. Yick.
