Most people know you cant sell every item in the market, but the recycle option would change that. With the recycle option any full stack of stuff your holding when clicking the "recycle" sign would be sold for, lets say, 10$. Any items available currently at the market would be sold as there price. For example, selling a stack of moss cobble would give you 200$ instead of 10$ because its already in the market. This would allow of abundant items to be sold really cheap. I hope one of the staff reads this.
