When there's not any on the shelf at Walmart, go find an employee and ask them to check. At our local store, the pick list (the list of items that need to be pulled out of the back storage cages of items that need to be restocked on the shelves) doesn't get printed until 7 or 8pm, and it takes a couple hours to pull the list. Then its not taken out for night shift to stock until 10pm or so. Our store services anywhere from 50,000 to 80,000 people and is virtually never out of stock of it, just not on the shelves, but we also don't have a lot of crafters in this area LOL
