I've seen my local supermarket doing that with toilet paper recently. They were out for as long as everyone else and now there are these massive blank cardboard crates filled with individually wrapped rolls like you would see in a hotel or office. So some clever buyer got creative with the supply chain which is awesome.
One of the local stores here in northern NJ has started doing that as well. They are doing the same with facial tissues.
Smaller stores are likely more agile in this respect, because they don't need to rely on the items having bar codes and entries in their central inventory system. That's what tends to hamstring large, centralized retailers.
Meanwhile, my local Target is still sold out...
