Mute if they don't sell try geartrade. I sold old stuff there (jacket & skis). They send you a box with a lable to ship back to them free of charge (they're based in Utah). They list it on their site and when it sells then venmo you the $$. These will probably go quick. They give you a price when they get your gear but you can adjust the price higher or lower. Doesn't code you anything.
