Thanks SO much to several of you for taking the time to share this one!
Today only on the Urban Decay website, all Revolution Lipsticks (original, matte and sheer) are $11 each (regularly $22). You MUST be a UD Junkie to get this discount (free to sign up HERE) and if you're a UD Junkie, you also get free shipping on all orders! Once you're signed into your UD Junkie account, you''ll see the discount in the item listing.
Thanks again to everyone who commented on the blog and emailed me about this today. I am so grateful for the tips!
