A few years ago I purchased two fifty sheet boxes of 8"x10" Tri-X film as well as a twenty-five sheet box of Ilford Delta 400 in 8"x10" size (all being stored safely in my garage freezer). I am so glad that I did because the cost of film has sky rocketed since then, and the Delta 400 is no longer even made in that size. Now 8"x10" Tri-X only comes in ten sheet boxes at the outlandish price of more than six or seven dollars per sheet! I can only expect the prices to go up since everything else is getting more and more expensive. By all means, do yourself a favor and stock pile NOW!
