Thousands of tubes for sale

I'm currently a solid state guy but just a few minutes ago when looking for a used wind trainer for my bike on facebook  I happened to stumble upon this post. Not knowing any better I thought it might be useful to someone on the analog side of listening. The ad is for sale thousands of tv and radio tubes. I don't know if it has any relevance but if it does someone could be very happy I posted this.
