I remember selling Fuji 35mm 36exp film in the early 1990s for IR£2.99. (Irish Punt before the Euro)
Now calculating for inflation that would be, in todays money, IR£5.86 which since I now use Euro would be €7.44. Today I sell the same film for €4.66, thats 37% cheaper than the 1990s price and that was when film was in its' hayday.
IMO I think the price of film has never been cheaper, even with recent price increases.
