Recently looked up the ad for this comsestic product? Nope. Not at ALL! And yet, ... cue spooky Twilight Zone music.
Today I decided (didn't even say it out loud to anyone, just thought it) "Hmm, I should try that product again, wonder if it's still here." And it was. So all day I've been using it, to see what I could see.
And sure enough, I go on FB, and ... yep. A big old ad for that very product on my page. An ad I haven't seen in a long while.
A very odd little coincidence.
