Sephora's Friends & Family sale started today and runs through November 2. Just use code FF2009 to get a 20% discount applied to your order. The discount is good for nearly everything.
This morning must have been gangbusters at the site. I got a "site busy" message early, but was able to place an order later. The offer is good online at Sephora.com. As far as I know, this sale is only active online.
