HÄagen-dazs

This weekend, I bought it for the first time in over a decade.
  1. WHY am I seeing personalized ads for it?! I have never had Häagen Dazs ads before.
    Twitter, Fb, AND Instagram
  2. I didn't post anything about it on social media.
  3. I did use my debit card to pay for it.
  4. I didn't use a coupon or anything.
  5. I didn't google it first.
  6. I didn't look it up on Amazon.
  7. I did talk to myself about it briefly at the ice cream freezer.
  8. Somebody help explain this to me, because it's kind of freaky.
