Single post in $ The Unofficial Item Pricing Guide $

Pretty much what it means is how much that certain user prices the item at. If a person collects, say Ice Statues at 20zc, that is their collector’s price. If someone collects the same but at 50zc, that is the other person’s collector’s price. Usually their forum signature or abouts would talk about how much they collect each summon at, but usually if it’s a first time, they would provide how much their collector prices are.
