J.Crew is offering two different free shipping codes right now.
Enter SUNSHINE to get free shipping on orders of $100 or more.
Enter HELLOSUN to get free shipping on orders of $150 or more.
I love J.Crew's campaign coupon codes - they come up with some really cute ones, and they are much more interesting than just "Free Ship" or "JCrew Ship 100" or something like that. Both codes are good until May 13, 2009.
