  • Protect your privacy online—and see better prices doing it

    But even controlling for price changes for issues like demand or technical delays, some retailers still display different prices from person to person, said Christo Wilson, an assistant professor at Northeastern University in the College of Computer and Information Science.

    While some of the pricing changes are immaterial, Wilson said that the personal data the companies get from the purchases could be an end in itself, used to edge out the competition.

    “It appears to be about incentives,” Wilson said. “If you’re logged in you get discounts. This incentivizes the user to do something … [because] it’s easier to track you this way. Every company wants to be on the data bandwagon.”
