An online flea market or bulletin board (https://kupika.by/) is a website or platform where people can buy, sell, or trade goods and services with other users. It is similar to a traditional flea market or classified ads section of a newspaper, but it is all done online.
Users can list items they want to sell or buy and communicate with potential buyers or sellers through messaging or comments. Online flea markets and bulletin boards often have categories or sections (https://kupika.by/catalog/) for different types of goods, such as electronics, furniture, clothing, and toys.
Popular online flea markets and bulletin boards include Craigslist, Facebook Marketplace, eBay, and Letgo. These platforms provide a convenient way for people to find bargains and get rid of items they no longer need.
