Update: this widget has been replaced with this page: http://www.forumvancouver.com/pages/vancouvergroupbuy/
Hopefully you've noticed a summary of the Daily Group Buy sites (Groupon, Grooster, Wagjag, Steal the Deal, and Team Buy) on the left hand side of the forum. I added it when I couldn't update the group buy thread manually.
It's also viewable here on the blog on the right hand side!
The "widget" draws upon an RSS feed that I created by using a tool to extract the relevant information from each website, so it updates automatically when the deal of the day changes. It goes a bit wonky sometimes due to the data extraction method but should mostly work.
The feed address is: http://feeds.feedburner.com/vancouvergroupbuy if you are interested.
