Wow, that’s the most name-full title we’ve ever published. Buy.com, which sounds like the typical dot-bomb service with a great domain and which never managed to take off, is launching an application called Garage Sale for Facebook which sets out to give eBay a run of its idea.
Garage Sale was built by the technology acquired by Buy.com through its acquisition of Shoperion a while back. Notably, the application is one of the first to implement a true shopping cart-system into Facebook, resembling a really simple version of eBay with an iFrame in Facebook.
Facebook users add the application, complete a simple signup process to the service, and can list an item — like they would on eBay — through its thoroughly simplistic interface. The problem of course, would be finding buyers, and with only 317 people having added the application so far, it’s worth noting that you will have to wait a little while before you manage to sell off that iPod mini. 
This is one of the first Facebook applications we’ve ever profiled in the style of an ordinary service or startup, and it questions a new trend: is Facebook Internet-style big enough to complete services and offerings to launch within it and face big tough guys like eBay? Of course, as is the case with Buy.com, the services that are launching are currently backed up by an established player, but it won’t be long till we see a paradigm-shifting, curve-jumping, patent-pending application (and here’s your reference) that changes the world — within Facebook.
You forgot to mention what a horribly thought out application this is - http://www.apprate.com/garage-sale-157/ I give it 2 out of 5 stars. There’s no way to search for items on sale except by visiting your friends profiles individually and the company takes 5% of your final sale price. Facebook Marketplace is much better suited to this functionality.
eBay’s Facebook application (eBay to Go) is well thought out and makes Buy.com’s Garage Sale look like a fun CS project. (http://www.apprate.com/ebay-to-go-widget-104/ for our review)
ok maybe now that I tried it out I understand what Andrew is saying but, their effort should be rewarded, because eBay has been in the spotlight for a long time…even though buy.com has the better domain name, and although when you surf the web its much easier to stumble upon buy.com than eBay, people were never that interested in it. But if you ask me; I think they should start be partners. Then maybe change eBay’s domain name?
3 companies doing one thing and i don’t know whay buy.com is challenging for but do ebay and buy.com already have what they want. well i guess that thing about facebook users buying things from ebay is pretty much a good idea.
