Now we're advised to wear masks? Who's selling them?

CBS News: Should we be wearing masks?

I did notice an increase of people wearing a mask today than I did yesterday. Other than make one, which I could do, where are people buying these masks? Those that I saw weren't homemade.

Most were the usual surgical/dental-type white or blue PPE masks. A couple appeared to be the white N95.

I did see headlines where both Home DePot and Amazon stopped selling N95 masks to the public because of a shortage of them at hospitals.  So where are masks available? They had to be purchased retail, they didn't order them overnight. They must have stocked up weeks ago or they know someone. Do I have to talk to a friend now, to buy masks? WTF?
