Went to 4 different pharmacies, 2 of them enormous. Couldn't find any masks/respirators on the shelves. In each case I asked a store helper person. Only in the 4th one I went to did they have anything, and in that case there was only one type of product available - a disposable N95 respirator by 3M. They cost $5 each.
How are you finding masks and affording to stay masked all the time? It seems really expensive...
Amazon, currently. I pay about $20 a month for masks, and I often see deals on 3m n95s.
There are some medical supply places online where you can sometimes find deals on bulk masks. Haven't used any of those sites personally, by a friend of mine got about 400 3m n95 masks for about $150 a year ago.
Generally n95s are good for at least 8hrs of straight use from what I've seen. So if you are only grocery shopping or going on public transit or other relatively short time periods, you can re-use the same high quality one for a while.
