Interesting. I’ve never heard of this, but I understand cookies well enough to see how this can work. Great article!

Out of curiousity, I’d like to know of a site that’s doing this.

You said that you were “offered a different price or offer about 50% of the time when I used the computer full of cookies, and about half of those offers were higher than the price shown to me on the clean computer.”

Does that mean that only half the time there was a difference, and in those cases, only half were higher on the cookie computer, the other half of those cases, it was lower on the cookie computer? It seems like you have even chances of the cookie computer showing higher or lower prices.

I’ve noticed this with travel sites, too. I’ve done research, gone back to my partner to tell him of a price, then when I go back to the site to purchase, blammo! Higher price!
