I have an opportunity to buy 6 jugs of Fotospeed Gold Tuner for $50. They are from a guy I know in town. I've pretty certain they have been sitting in his outside shed for the past few months at least. I'm not sure the lifespan of these things. I don't know whether temperature affects, in a major way, the ability of the toner. If anyone has any information, please let me know. Also, would anyone be interested in snagging a few bottles from me? I will not be able to use six liters of gold toner anytime soon. Thanks for any response.
