Alright let's be honest now, when was the last time you've used an item that either had: no stats, 1 socket, crappy attributes, or anything else in that sort of manner? Most likely not for awhile depending on who you are, so now we bring a new feature to the shop: The Recycler! You can now throw your crappy items into the recycler and get a small lump sum of cash depending on the items.
How it would work, 3 items go in, the machine breaks down the hats and other items down to it's basic cash core and you receive the cash based on the regular hat value, or prices determined by current market value. This not only saves space for different inventory items but also helps by getting cash to spend on other important items.
