This afternoon, I looked at a shipping box on the Staples website, without logging in to any account on that site. (As far as I know, I don't have an account.) This evening, I get an email from staples@easy.staples.com with the subject "Yep: You had your eye on this, so we saved it for you." and the ad for the shipping box. Does anyone else experience this sort of browser tracking and targeted advertising? If I had logged onto an account on the Staples site, the email wouldn't have surprised me.
