There's an item in the NC mall called "Upcycle Fortune Cookie" -- when you use it you can donate your junk nc items to the money tree in exchange for more nc items or neocash. (not much nc back but it's something).
Yup, this is already going for a few weeks. I can't grab any NC items because they are gone way too fast. I really wish that someone can make a NC item grabber or something with this new feature.
Ya someone in my guild said this and I was like that is impossible. Guess it is not. I hope I get one.
