Buy a used stacked washer and dryer by locating a unit that meets your needs on a site such as Craigslist, eBay, Sears Outlet or ApplianceXchange.com. Depending on the site, you then either make arrangements to meet the seller in person or pay for the units online and arrange delivery.
Whenever buying a used appliance from a private seller it is important to conduct as much research as possible to determine if the seller should be trusted. When shopping for a used stacked washer and dryer on Craigslist, buyers are unable to perform much research on the seller unless he provides his name, phone number or email address. If you can't research the buyer, but you are still interested in the washer and dryer, exercise caution when arranging a meeting, such as meeting in a public or open space during the daytime. Buyers should always test the washer and dryer before handing over any money to make sure that both work properly.
Sites such as eBay provide more tools for researching a seller, including a comprehensive seller feedback system. This system allows any user who successfully completes a sale with the buyer to rate the experience and write a review. This also allows unsatisfied purchasers to warn other users of scams or fraudulent activity by the seller.
