Film is expensive when someone tries to use it as it was used up to the 90's for commercial work if we talk about constant sessions with hundreds of images per session, unless you're a very well paid photographer and nothing matters...
For amateur and beginner's use, and even for serious work with quality above quantity, film is not that much more expensive now, just a bit...
A few rolls a month give a few hundreds of images a month: IMO it's about getting some of them well done, and not about shooting more...
100 ft. rolls by Ilford are a lot cheaper than Kodak's, so thank you Ilford!, and Kentmere films, made by Harmann Ilford, cost even less, and they're great films...
I admire recent years Ilford's public commitment in relation to film photography, and I support them happily.
