Buy.com has launched a service that enables consumers to sell goods directly on their business and social networking pages. Garage Sale charges no listing fees and a flat-rate commission fee of 5 percent and is initially available on the Facebook site.

Checkout functionality is incorporated directly within the advertisement. On the Facebook application page for Garage Sale, it explains how it works:

"Simply add Garage Sale to your profile page and create a listing. When someone wants to buy, they check out on your profile page. Garage Sale bills the buyer's credit card and notifies you when billing is complete to ship goods. Sales funds are deposited into your PayPal account, or you can request payment by check."

The service markets itself as a way to "buy items from friends you know and trust - a great alternative to other online auction sites."

To help sellers promote their listings, Buy.com will introduce a Garage Sale tab on the main Buy.com Web site later this year.

Neel Grover, CEO and President of Buy.com, said, "As the first company to market with this embedded ecommerce capability, we see tremendous growth opportunities in providing the millions of users on business and social networks with an alternative to eBay and the ability to transform their personal profile pages beyond information-sharing."

The Garage Sale platform is based on technology from Shoperion Inc. that Buy.com acquired earlier this year.
