haggling means "dispute or bargain persistently, especially over the cost of something." I cannot explain bc im bad @ it but I can give an example
person1: "I want this adopt for 10 points?"
person2: "what about that adopt for 20 points?"
person1: "how about 10 points + art"
person2: "sure!"
(not sayin u have to pay in points for this situation, but I hope this example helps u understand what it means lmao)
