Costco offers home delivery of washing machines, but as of 2015, its website is only offering washing machines when purchased with a dryer. Delivery is included in the price, along with installation and removal of the old appliances.
Costco places some restrictions on delivery, installation and haul-away services. There is a PDF document on the description page of each particular washer/dryer combination, which provides details regarding what the delivery and installation personnel can and cannot do. Installation of gas dryers has restrictions that vary according to state and local regulations. A zip code list is provided to help determine if installation of gas dryers is permitted or prohibited.
