[Serious(most of the time)]

go to a NPC. Select the purchase option. Then click on whatever item you want to sell to the NPC. If you have mass quantities, you can right-click on one box and sell them all at once.


Also, just FYI, when putting stuff in storage, if you right-click the item with your storage window open, it automatically drops it into storage. This saves the whole drag and drop motion.

EDIT: also, please do not double post. Give it time and trust me, someone will answer you.

Sorry for the double post, and thanks.
