Putting up washers and dryers for sale is easiest done online or at a yard sale-style event. Online retailers such as eBay or Craigslist are useful for selling second-hand items, and eBay even has a useful guide for selling washers and dryers.
When putting washers and dryers up for sale, it is important to have high-quality, pleasing images in the ad. Sell the washer and dryer as a set, as this is generally how shoppers wish to purchase them. When listing your washer and dryer, consider how you plan to ship them, or if the buyer needs to arrange pick up herself. To set a competitive price for your washer and dryer, research the prices of other similar products on the website you plan to use.
