Let's do something to help put that $0.73 per frame on your 126 film cartridge into perspective.
(1.) You do not have any, but Blue Moon does, and you also know that they have not made 126 film in quantity for over 25 years now.
(2.) You will be able to get your camera back into operation. And, you can reload those three 126 cartridges, and keep your camera in operation.
(3.) About four years ago, Dennis Purdy had his 12 by 20 inches (NOT Centimeters!!) Large Format landscape camera out at Newport, Oregon. We calculated that it was costing him, at that time, about $25.00 just to load one of his film holders with a piece of film.
