I get anywhere from 12.5 to 16.66 bowls out of a 50 gram tin. Depending on the size of the pipe I use, group 4( 3 grams a bowl), group 5(4 grams a bowl) will determine how many bowls per tin I get. Now I smoke only flake tobacco so when it comes to different cuts, I have no idea for a ribbon or the like. When you figure out how many grams per bowl you smoke, you can figure the approximate cost per bowl. No matter what cut you use or how many grams per bowl, I think you will find, pipe smoking is the least expensive way to smoke tobacco. My most expensive blend is Capstan Blue and at 12 bucks a tin, smoking a tin in a group 4 pipe, it will only cost me .75 cents a bowl which for me is the most expensive tin I own, that is a damn good deal. For 75cents, I can get an hour and a half of smoking pleasure smoking the most expensive tobacco out there. When people look for bulks to save money, think about smoking something that you are just ok with instead of something you love, just so you can save 30 cents a bowl.
For me, I would much rather spend the extra 30 cents and smoke what I love. 30 cents is not going to alter my lifestyle in any way shape or form. I seriously doubt, 30 cents is going to alter anyone elses life style either.
