I'd been wondering what they did with all the "Answer these Questions to Find a New Survey" answers since they don't seem to serve any purpose in getting me more surveys for which I qualify. They're certainly collecting enough info about where I shop, what diseases I have or don't have, etc.

Yesterday I was asked to check off what stores I'd shopped at in the last 6 months. I checked off Kroger, among others. There are no Krogers anywhere near me but I was visiting family in SC last month.

Right after that my FB feed showed a Kroger ad. Yep, the information is all for sale.
