Show HN: Per Frame – film prices compared by cost per frame

I'm into film photography, and I built this tool to help me find the best price for a given type of film.

I'm currently tracking 185 films across formats (35mm, 120, 110, 4x5, Instax Mini, etc.) from 7 stores.

This is US only for now. If you shoot film I'd especially like to hear about stores I'm missing or anything that's wrong.
