They have been moving well at the Wal*Marts in my area as well. As frustrating as it is to see the empty shelves, it's good at the same time - With VvV selling out, it is possible Wal*Mart will want to continue ordering the product, and we will get the new waves.
If not, Corey at smalljoes gets my buisness, as he only puts what he has physically in stock on his site. If you've ordered it, you *will* get it.
