Well, there have been many posts disagreeing with the PR's of single stores in various countries, so I can see why we wouldn't see as many. Not saying that Eric bases his decisions off what he reads here, but I know he may change a few things.
Another thought, the new store locator really speaks for itself now. I think at this point it would be foolish to release a "Single" store or location PR, when we can wait until we are above 4000+ stores and release that news to the masses that already don't know.
