Well, I just pulled up Freestyle's website in the Wayback machine for what I assume is the year of your birth, and let's see. (and oh boy, I forgot about Kodak's old packaging from that era)
Neopan Acros, 135/36exp—$4.49
Delta 400, ditto — $4.89
TMax 100, ditto — $4.99
HP5 — $3.59
Fujicolor NPH400 — $5.99
Portra 160NC — $7.59
And I could go on. Amazing too how many color stocks are gone. So many different Superias.
Plugged some of these numbers into Inflation Calculator and...they're not far off the prices today (e.g. HP5 with inflation: $5.19; current price at Freestyle: $5.99. Portra at $10.98 vs 11.24)
So at least since I've started shooting in earnest, film has decidedly stayed mostly the same. Hopefully some of those older than I, or at least with older catalogs, can chime in.
But supports my original point. Even processing—a decade ago when I was between darkrooms, developing BW and medium-res scans at Hunt's in Boston was around $12-14, about what places now seem to charge.
If anything, I'd say shooting film, as a pursuit, is cheaper. You can buy pro gear for a fraction of MSRP, develop at home, and scan with a slightly older digital camera, and your cost per roll comes down to...very little. I don't exactly miss wet printing, and I trust my inkjet prints to an experienced local lab who is shockingly inexpensive for exhibition grade work.
