Provia and Velvia are not significantly more expensive than professional negative films, at lest not Portra and Ektar. I just checked Freestyle and Provia is actually slightly less than Portra. There are no cheap amateur slide films from Fuji anymore though. The death of slide film is due to vast improvement in negative film and consumer preference, not price.
