when did I do this?

This started a week or so ago. At first they just said I had shown an interest in jerky. yesterday it was "meat snacks" and today they've added pepperoni. which, I guess I do like, but I don't remember ever looking at them on Amazon.

I think maybe they're spying on me and know I've been drooling over the Jerky Outlet billboard on I-30. (I looked for a website, but they don't seem to have one. However, this lady claims to have been there, so I know I'm not smoking crack.)
