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.

Who is affected
Identify the existing workflow this change affects before recommending an upgrade. Launch attention does not establish improvement; an API, pricing or availability change may instead create migration work.
Missing comparison points
Missing checks: old versus new behavior, affected plans and regions, availability date, compatibility, rollback path and cost under the same workload.
Migration check
Save the release or policy notice, run the same task on the old and new option, and compare outputs and the full bill. For retirement notices, verify the deadline before scheduling migration.
