I bought more fuji fp100c45 than I needed two years ago and the prices have doubled since. Polaroid hoarders are being rewarded, especially the people who saved their 8x10 processors after knowing Polaroid would never make the film again.

I've bought plenty of Kodak 4x5 and 8x10 film that has gone up 25% in the past two years; such that I would be hesitant to buy it now, but gladly use what I've got. Their 120 format stuff has stayed pretty stable in price over the past two year, but I still hoard it in case Kodak continues to make bad business decisions.
