Didnt Orbitz (or one of the travel sites) get caught charging customers more money per ticket if they were on a Macbook vs any other computer? [1] This type of data collection is the start of individual pricing based on what stores believe you will pay.
I don’t believe they were offering the same hotel room at different prices but rather more pricier options to different users. From the WSJ article that is the source of the CNET one:
“ Orbitz executives confirmed that the company is experimenting with showing different hotel offers to Mac and PC visitors, but said the company isn't showing the same room to different users at different prices. They also pointed out that users can opt to rank results by price.”
Stuff like this annoys the hell out of me. They should offer the same things at the same prices to all people. Same in Us healthcare. A procedure will has a several hundred percent price variation depending on insurance and other factors of the patient.
