Confirmed. A few days ago I picked up the last box of ramen on the shelf at my grocery store. Since then I have seen none available.It varies, depending on the store and the market. The bigger stores (Costco, Wal-Mart/Sam's Club, Winco, etc) are optimized for high sales volumes and have the infrastructure to resupply large quantities quite quickly as long as there is product in their warehouses. The smaller stores, particularly independents, are having more difficulty keeping up with the overwhelming demand.
Intersting thing: For the past couple of weeks the hottest items have been TP, bottled water, and hand sanitizer. Now, in just the past few days, the zombie hoard has turned its attention to Top Ramen.
