I ended up just sticking my polaroid back in the fridge - I figure that I might have to let it warm back up again for about half an hour before using it.
No, there is no Amazon Australia unfortunately. If I want to get stuff from Amazon US then I have to use a mail forwarder or a relative/friend living over there to get somewhat reasonable postage rates as they charge an arm and a leg for shipping overseas. A quick browse on eBay shows some prospects, but it's still kind of expensive and not in the bulk I can get ordering from the US.
The Japanese one is an idea, though a quick look at Japan Exposures have prices similar to local, and that's before shipping.
I was in contact with another member who was offering to sell me some FP-100B, might end up ordering a big pile from him and then clog up my fridge with it lol.
