This just popped up in my email today, sounds like it ends soon. Btw, I have no affiliation with this site. Unfortunately, it is not retroactive to my purchase but I know air compressor posts are popular on this site and Viair comes up in all of them. Just an FYI, and, please, if this is not allowed in the forum mods remove or move.
