Groupon has some terrific deals for a one day or weekend pass to the 2013 Northwest Chocolate Festival on September 21 and 22. I haven't yet written a posting about this year's event, but here's info about the 2012 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 $18 (vs. $35) or a full weekend pass for only $30 (vs. $65). They also have some additional options for multi-person passes. This is my favorite chocolate event of the year, and this offer is likely to be the best price you'll find to the event. I'm going to try to get some free tickets to give away again this year, but no guarantees.
UPDATE: This Groupon is no longer available, but they have a replacement Groupon with with the same deals for one-day passes.
