Usually when a great code like this comes up for one of our favorite stores we say encourage you to rush over and shop while the shopping is good, but rather than insipire hare-like behavior with this code for an extra 20% off final sale items from J. Crew we're going to ask that you instead follow in the steps of the patient tortoise. The code lasts through 12/28/2011 and we're guessing that they're going to add a lot more lovely clothes to the final sale after the 25th (and you might have gift cards to spend at that point as well). So bide your clever time and use code MUSTSHOP when you can get the most bag for your bargain buck.
