Let me add that the places where the advertising is most prevalent are the places where you see it on the most shelves.
In South Florida, where I live, we have the Marlins, and the Rays, and a lot of fans. I can't remember if it was the CVS website or Walgreens, but they had a search tool to see what stores near you had the product in stock. Within 10 miles were 10 locations. That is a tool anyone can use to see where they are right now.
