The B&H site has the 36 exp. rolls discontinued, but still has 24 exp. rolls. It looks like Freestyle still has some 36 exp. rolls, and has 24 exp. rolls on order.
Not sure if that means all 36 exp. rolls are discontinued, and only 24 exp. rolls are being produced (and Freestyle has some old stock left) or B&H is listing it as discontinued prematurely. I seem to recall we've had threads about B&H listing products as discontinued that aren't, they just couldn't/wouldn't stock them anymore. It's also possible the 36 exp. rolls at B&H weren't selling, or the press packs at Freestyle weren't either, and they've just decided to not stock them anymore.
