Living Social has a terrific deal on now for a one day pass to the 2012 Northwest Chocolate Festival on September 29 and 30. I haven't yet written a posting about this year's event, but here's my posting about the 2011 event and you can read about this year on the Northwest Chocolate Festival website.
You can purchase a one-day pass for either Saturday or Sunday for only $15 (vs. $25 at Chocolopolis, $28.77 online, or $30 at the door). NWCF is my favorite chocolate event of the year, and this offer is likely the best price you'll find to this year's event. Groupon had a similar deal a few weeks ago. The deal is scheduled to run for two days, but may sell out before then. Here's a direct link.
