Just thought I'd put out a bit of news I've heard consistently enough to deem valid.
People are starting to find these in stores again; and not only that, but each store appears to be getting more than just a case or two. I've seen a fellow collector report seeing as many as ten on a shelf at one store.
Also, for those who are tired of going to the store, these occasionally show up on Walmart's online store. You can actually have the item shipped to a local store, meaning you don't have to pay for shipping. Some people like to argue you still have to drive to the store; but I'm not in the camp that believes that's a good argument.
