A bunch of the companies have gone out of business and it's much, much harder to get than it previously was so whether they sell them or not isn't the issue... it's the companies that make them that are having a hard time. Some of them have entirely shut their websites and operations down already.

TIL they are still called poppers - I am surprised there isn't a new slang term. We snorted gallons of the stuff in the early 80's and collected the empty bottles. I have to admit, it makes me queasy thinking about how much of the stuff we went through. It's fun on the dance floor too.
