I don't mess on my tailor anymore but at one point in 2012 even I was buying bone for 150 per lol :/ couldn't even find a farmer to fill orders so I gave up lol I'm not buying em anymore but I'd think due to lack of bone farmers you might have np getting 100per but im not positive.
where did you see gheal on a vendor for 300gp per?
Some people actually pay up to 5k per charge...
