In planning for a long term film project (which I am now undertaking) about 4 years ago I bought loads of Portra 160 & 400 in 120 and some in 35mm, I also bought a selection of other colour and B*W films fo rother stuff plus a heap of Provia 100F, I think by good fortune I got in just before the prices started to rocket. I have it all in a freezer and just take out what I intend to shoot the day before the shoot and pop it into the fridge overnight then load in the morning. My biggest difficulty now is getting my Provia developed and scanned, the place I used to use has downsized and no longer does E6, despite searching and trying others I have yet to find someone I am happy with. It is expensive testing labs. I currently budget for 1 film a week around £20 for dev and scan but I don't actually shoot a film every week so I carry the budget over to my project fund for when the pace picks up.
Long winded way of saying no the current price isn't affecting my use,,,,,,,,, yet.
