Ivory Albinos were being sold last year for around 2k, but I have seen 0 of them around this year . . . I'll message a couple of guys that I know with them and see whats going on. If I remember correctly, bob clark even stopped producing / selling them knowing that there seemed to be an issue once they hit a certain point.
Platinum is like the "lesser" gene in ball pythons. Its an enhancer gene and it brightens things up to make them better. Platinum is one of my favorite morphs. Ivory Anery is probably my favorite combo of them at this point. Most of the platinum projects for mainland have been tapped into by this point. Even things like the worlds first Platinum GC Cow will be produced more than likely this season or next. Some under touched things will involve Anthrax, anthrax is such a cool gene, even the visual het "granite back" does some incredible things to the mutations it plays with. And there has been no issues up to this point. Heck, Albino Anthrax was just hit for the first time this year! Probably not even 4 months ago, by NERD ...
Anyways, good luck and enjoy the addiction.
