Rue la la is offering a $20 credit off any $20 purchase!!! They have quite a few items that are $20 so will be free plus shipping. They have some beautiful things on their site (I have my eye on some of their jewellery) and items are apparently added every day. Your credit will show up on your account about 48 hours after registering with them and you can use it anytime before 12/31/10.
Just click here to go to their site and register.
