Honestly I agree with you. If I see several of the item I want I go with the lowest depending on if I need it or just want it, but if I need it like for a mission and there's only 1 person online I don't even bother haggling I decide if I'm willing to pay that much and if I am I offer. Honestly the Rusty is expensive to get because of the levels requiring restaurant foods. I've never understood people wanting potions or enchanted plushies to cost less than what it cost the person who got them paid for it honestly.
