I consider Google Base as a site for online classified ads like the Craigslist. Some bloggers call it as an online marketplace like eBay without the auctions.
Google describes Google Base as “a place where you can easily submit all types of online and offline content that Google will host and make searchable online”.
You can use Google Base to post items that you want to sell; other users can search the Google Base database to find items they want to buy. When a match is made, you and the other user arrange payment and shipping between yourselves.
