I've been wondering about this for a while but there's a lot of mats that other professions use that only need 1-5 at most, but the market only has people selling 99 of that item and obviously overpriced.

Why don't people just split up their 99 into 5s or something? I'm doing this but overpricing each piece because well.. it's either buy my 5 mats or buy 99 of something you don't want 99 of...
