I still see a fair number of N95 masks on Amazon with "free" shipping to HK on a min US$49 aggregate order. But you have to search "n95" only. Search "n95 mask" and you don't get much. Still, who knows the situation tomorrow.
Obviously the Government should just buy 100 million masks and hand them out on street corners.
The government is known to do the exact opposite of what it should in almost every situation lately.
