That sucks bro. Thanks for contributing. I wonder how he would feel if you paid him half his money for his oils? Not good at all i bet. I hope they make a "wall of shame" for these pricks. It would be for all the underdosed gear these guys sell. Put them on blast.
Better be a damned wall the size of the Great Wall of China. Ironically, that's were most of the half dosed raws start, anyways.
