Used jet ski floating docks can be sold on a number of different classified advertisement or auctions websites such as Craigslist or eBay. These websites allow users to post classified advertisements that other users can search through, bid on or purchase directly through the site.
It is possible for anyone to post an advertisement on e-commerce sites such as eBay or Craigslist. Craigslist is a traditional classified advertisement site where users post items, information about the items and an asking price. Anyone can contact a seller on Craigslist, and if the two parties come to an agreement, a transaction is made. eBay is different because it is technically an auction site. Users post their item on the site and set a minimum price, and then the item goes on live auction for a predetermined amount of time. Other users of the site bid on the item, and the highest bidder ends up being able to purchase the item at the end of the auction period.
To post a used jet ski floating dock on one of these sites, take pictures of the dock and determine a price-range that the dock would ideally be sold for. Go to the "Sellers" or "Posting" end of one of these sites and create the advertisement with information on the item and contact information for interested buyers.
