A method and system of using widgets embedded in web pages as virtual storefronts is disclosed. A user of a social networking site may create a merchant account with a transaction service provider. The user embeds a storefront widget provided by the transaction service provider in the user's profile page on the social networking site and the user can use the storefront widget to input information about products that the user is selling. Other users of the social networking site view the user's profile page and the storefront widget will display the products that the user is selling. The other users may interact with the storefront widget to purchase the products that the user is selling.
