I have had this happen quite a bit. So has my wife. And other family.

We were once having a conversation while in Woodland Park about seeing a chiropractor in FtCo. Boom, an hour later, ads for chiropractors in northern CO. Nobody ever searched for or visited any chiropractors in FtCo...

Wife took the baby to the Dr. He got some cream for a rash. A free sample, not a Rx. I got home and asked her what he was given. She said "I don't remember what it's called but he got some cream for.." so-and-so rash that she described using the proper medical term. What do you know, I get ads for the exact name brand rash cream we were given. Nobody in the house ever used the web to search for or research the condition or the cream in ANY way. And no money was exchanged for it. NO way that's a coincidence.

And many examples too. But to be fair, I see many more ads for random stuff than I ever see that I think are targeted based on digital snooping (which there is no doubt in my mind exists in far greater reach than anyone will admit).
