For those who haven't, sign up for Coterie: https://www.coterie.com/refer?code=TO6NwoCxI
(or if you have an account this works too, but if you don't, I'd love
it if you signed up thru me) then go to My Vanity, add a Butter London
polish to your cart, use this code: DEMETERVIP and it's free, takes
shipping off too!
I don't know how long this code will last but it worked for me, so act fast!
EDIT: Polishes are sold out atm, but I think the code is still good for 20 dollars off something, I think, worth a try.
