Another ad issue: a pop-up from Kohls.

Chrome's pop-up blocker flagged something on HTF, so I investigated since you don't normally use popups. It was an ad that triggered when I went into an HTF thread.
Not a big deal to me, since I have browser's pop-up blockers on by default. But in case you were unaware of popups from your advertising system.
