Well, I can't quite remember my best trade so I will post my worst one. I was in Varrock bank while doing Gertrude's cat quest the first day the quest had come out so I didn't have a guide for it. I knew I needed doogle leaves but I didn't know where to find them. I said I was buying doogle leaves and I traded with a guy who said just offer for the leaves. I had no idea what they were and put up an addy plate, an addy 2 hander, and a mith 2 hander all for doogle leaves which were right outside the bank I was in >_<
