That happened to me about a year ago when I needed a box of Carol Shelby chili mix. Shelf was completely bare, asked the store mgr. when more would be in, and was told that there had been a recall on the mix, due to a problem with finding some kind of foreign object in a batch. So until all the machinery at their plant has been thoroughly inspected, all products had been recalled. None had gotten out to the public, it was caught in a quality control check at the plant.
