From NARS to Fenty, here's how to save at the surprise Sephora sale

This is not a drill. In celebration of its newly updated Beauty Insider program, Sephora is having an exclusive sale for its loyal customers, aka all of us. Here’s everything you need to know before you start filling your carts.

If you’re a Rouge member, you get 20 percent off everything in store and online (with the code YESROUGE) now through Monday, September 3.

If you’re a VIB member, you get 15 percent off everything in store and online (with the code YESVIB) beginning Thursday, the 30, through Monday, September 3.

And if you’re an Insider, you get 10 percent off everything in store and online (with the code YESINSIDER) starting Thursday, the 30, through (you guessed it) Monday, September 3.

Now, the fine print: You can use your discount once online, but as many times as you want in-store. The offer extends to Sephora stores that are located inside JCPenney (but not on jcp.com). The only brand exclusion is Dyson. And you’re capped at three Drunk Elephant and Tatcha products per transaction. Now excuse us, we have some T.L.C. Framboos Glycolic Serum to buy.
