My wife was in a pretty typical Walgreens today and noted that there was a sign in front saying that they didn't have any masks left and that they didn't know when they were going to get more. Inside, there were a number of sections besides masks that were completely empty. This Walgreens is in Mountain View, a few miles from the main Google campus in California.
