While reading somethings about RMAH, a question came up. This is a question for people who says they will never use AH/RMAH and just play with friends and exchange items.
So you formed a group with your friend to kill a boss and the boss dropped a chest piece that no one can use and you won it (we don't know how loot works yet but we can leave that part out). The chest piece is worth 10 dollars on RMAH and your friend found out by checking some RMAH mod and he offered 50g for the chest piece with the intention to resell it on RMAH.
Assuming you have no intention to use AH/RMAH at all, what would
you do in this situation?
This question doesn't apply to anyone who plans on checking prices on AH/RMAH of course. This is only for people who wants nothing to do with AH/RMAH and only trade/sell as he/she sees fit with friends.
Edited to make question more clear
