18% of all items previously stocked in the US are out of stock. This is mainly brands or niche items. For example, gold peak green tea is out everywhere, but there are still other green teas and other gold peak products. The supply chain has broken down for specific items. Most stores just expand what they have to fill the gaps. It is not, so much, that they are running out of Food, but more that many items that were highly coveted before, are not available now.
