Right now you can get a $20 credit to the daily deal site Rue La La when you sign up through this Paypal link. The credit should show up in your account within 48 hours.
I would highly recommend signing up for this credit even if you aren't sure if you'll use it. They had a similar offer last fall that I passed up and regretted numerous times that I did as there were several really good deals that I could have gotten with it. If I see great deals for Rue La La I will try to let you know.
Thanks Money Saving Mom!
