Use this Paypal Invite to create a new Rue La La account and you should get credited $20 within a few hours. I already have a Rue La La so I was not able to test this myself but if it works for you make sure to let us know. Just remember that it takes a couple of hours for the credit to show up.
When this credit was available in the past people were able to use it even on shipping, so it made for some great deals. Rue La La has some nice fashion and home item deals, so hopefully you will find something to use your credit on.
THIS PROMOTION IS EXPIRED NOW.
