for anybody that didn't notice not only does the npc in tailor richards take durty undies he takes those discarded scarfs as well. So if you haven't figured it out npc's that have some sort of relation to the loot you pull up buy them. I.e blacksmith in snow buys weapons, little kid on beach buys shells,fish related stuff, tailor richards, clothing/fabric, pyrate on boat near york fort buys dabloons, rafeal in the black ordchid buys mugs, floydian (fisherman in south swamp buys fishing equipment,and ester buys everything. I'm still looking for others who may purchase loot.
btw I thought the prices where okay but a small increase doesn't hurt.
I also think its better to sell stuff individually in the long run instead of all at once to ester.
