For those who live in or near DC, today's Groupon is for
Stitch DC. You can buy $20 worth of knitting materials for $10.
Here's the Fine Print: Expires Jun 13, 2011 Limit 1 per person, may buy multiple as gifts. No cash back. Not valid with other offers. Must buy prior to midnight Sunday (12 Dec 2010). Oh, for those who have never used Groupon before, just because you buy the groupon doesn't mean you have to use it by tomorrow. I think it expires in June 2011. Also, you can refer friends for extra discounts.
Hope that helps!
