In any case, kama-making from mobs hunting is a by-process while leveling your character

The problem though, is a lot of people are trying to make a quick buck by pricing some of these resources a bit too high, especially if they are selling Runescape Gold just one or two.

If it's a rare or high prospecting drop, I agree that they deserve a more premium pricing per unit but it wouldn't really make sense if you are just trying to get rid of stuffs you do not want. In any case, kama-making from mobs hunting is a by-process while leveling your character and doesn't really require any additional effort, nor does it really make you rich.

If you can drop it easily, others could easily drop it too and just because you were training on the mobs and conveniently getting these drops doesn't really make it right that you should try to squeeze every possible drop of profit.

It will maybe earn you a tiny pile from time to time but I guarantee it wouldn't be consistent unless you are actively hunting these specific resources and constantly churning out batches upon batches of, let's say Gob-ball Horns.

The bottom-line is that it will give you a spike in kamas and tide you over for a while but never actually enabling you to have any form of breakthrough unless you work hard at it.
