On the heels of last week’s launch of the premium Group Buy plugin for WordPress blogs from GroupBuyingSite.com, GetShopped has launched a similar but free (for now) group-buy plugin that works with the popular WP e-Commerce plugin.

You’ll remember that Groupon itself started out as customised WordPress blog, so if you run a blog for your brand or business – why not monetise your efforts by hosting Group Buy deals?  The GetShopped Group Buy plugin comes with a Groupon styled theme – and is an early beta version, so it’ll need testing and optimising before going live on your blog, but it might just be your quick social commerce win for 2011 (download here).
