Cult Nails is an indie company run by a nail blogger who decided to create her own line. I have a couple of her polishes--Quench and Living Water--and I really like them. They're great colors and have a nice formula. Over the Labor Day weekend (September 2-4), she's got a 2 for $15 thing going. Given that normally a bottle goes for $10, it's not a huge deal but it's not insignificant either.

The codes for the sale are on the sidebar of the main page.
