The owners retired. They were planning on selling provape to Mike (HOH), but his investors backed out because of the deeming regulations and the markets (vapers) reaction to it. People stopped buying like they were and began stocking up on mechanical
mods and such, when provapes sales dropped like they did, the investors ran and took their money with them... he couldn't find anyone else to loan him the money in that environment so he never bought provape, and the owners (as they were planning) retired.
