If your item isn't selling, it may be because the price is set too high. One option to push this inventory out the door is to drop the price of your items! Dropping the price of your items will notify any users who have favorited your items that you've lowered the price. It will also bump your item back to the top of browse.
From your item listing page, simply click "Price Drop" and then select either a 10% or 15% price drop, or manually enter the new asking price for the item.
Please note, you need to drop your price by a minimum of 10% in order to notify potential buyers that you've lowered the price. You can also drop the price on your items from the item thumbnail in your locker:
