There are several online marketplaces where users can offer items in exchange for other items. Examples include Craigslist, eBay Classifieds and U-Exchange. When using online marketplaces that allow users to negotiate trades directly with each other, one must take precautions to be protected from a small number of unscrupulous users.
Traditional newspaper classified advertising is a good place to trade a car for a motorcycle within a local vicinity. Online marketplaces allow buyers and sellers to communicate instantaneously, beyond the local community, throughout the nation and even worldwide.
Research the seller or trader. For instance, review an EBay user's feedback page, which includes scores, comments and other users' levels of satisfaction. Always ask detailed questions about an item that is being traded before committing to make the trade.
