I'm not going to post a lot of deals today, because my internet access while staying with my parents is spotty, but this one is interesting. Extra 20% off things in the sale section on the Sephora site today with code EXTRA20. The Bite Beauty holiday sets are marked down there: the huge Discovery Set is down to $40 from $55 and you get an extra 20% off on top of that. I used a gift card to pick that up. The Bite duos that I posted about here are marked down to $10 from $14 (+ 20% off). Unfortunately the dark berry one I have is sold out, but the others look interesting too. And of course there is a bunch of other stuff in the sale section of the site, including the Urban Decay Vice4 palette.
Remember, you can get an extra percentage off using Ebates, too--right now it's 4% at Sephora. (Here's my invite link.)
