Oakley Holbrook ruby iridium lenses?

Ok, so I have a pair of the polished clear/chrome iridium Holbrook sungles and I want to get another set of lenses for them. I really want to get the ruby iridium lenses, but is there anywhere that sells them for cheap other than oakley at $55? If I can't find cheaper than I will just buy another pair of sungles and swap the frames because I work with a company that gets me wholesale price on gles. I would only be paying $5 more and getting a whole nother pair of gles. But I was just hoping that I could buy the lenses for cheaper because I don't really need another pair of gles and I won't ever wear the other pair.
