Generally when the color of the caps change it is A) for a contest of some sort, or B) for rotational purposes (who can't rotate the orange to the front if all you get are blue.). The Kosher caps more than likely will be right in the front because they are for such a short timeframe there really is no reason to rotate into the shelf. Besides that consumers will set all of the HFCS bottles in the floor and dig to the back to get them anyways.
If what you did yesterday still looks big, you haven't done much today.
