Was it in the flyer at that price or did you just see it in your local store? I've seen my local CT sometimes have sales that weren't in the flyer, and then it turned out to be just that one store. They did that with Redline SI-1 injector cleaner a couple of years ago, it was half price just at one of my local stores but not the other ones, and wasn't in the flyer.
