UPDATE: I've just heard from several of you that this code is no longer valid. My apologies!
Now through 8/31, enter code MAKEUPSHOWNY for 30% off sitewide on the NARS website. Free everyday shipping on all orders (no code required), but tax will of course vary depending on your area.
Thanks again, @makeupblissness and @makeuplunchanddinner, for the awesome tip!
