Logging out of Facebook doesn't mean they won't be able to track you. Your browser fingerprint is likely tracked.

If you visited the manufacturer's site, you would have hit a re-targeting pixel for the network, that will track you around the internet to remind you. At work, on your phone, at school, and at home.
