For small business owners that want to sell products online, there are many different options to setting up an online store. One great option is to use one of the many free shopping carts that are available online. These include popular shopping carts such as OsCommerce, Zen Cart, and Magento. Each of these shopping carts are well documented and have a strong community of users and supporters who contribute add-ons and modules that can be used to enhance the existing functionality of the shopping cart.

Although these shopping carts are fairly easy to install, they do require some technical knowledge in setting up a database and doing the basic configuration to get it to work. However, once the shopping cart has been setup, the administrative features of the shopping cart make it easy to add and update products, track customers, and integrate various payment solutions, such as PayPal and authorize.net.
