Most people I know spend more at the bar than my partner and I spend on film and development; she shoots Polaroid, and we both do 35mm. Hell—we've spend more feeding our two cats than I've ever spent on photography stuff. (;

I'll also note that I find ways to spend less. Rodinal at 1+100 is a little cheaper than other development methods. I scan film at my university instead of spending money on a scanner. I also shoot very slowly, so I don't use that much film. I also don't like G.A.S.—all of the time I've spent looking for a camera to buy is time I could've spent taking pictures, processing and scanning film, etc.
