I wish they could do one for other NARS websites in other countries, especially since people not in the US end up paying more than the US prices thanks to taxes and other reasons I don't quite understand. ^^
I was at a NARS counter a couple of weeks after this sale and mentioned it to the SA. She had no idea what I was talking about and her jaw dropped at the prices I paid. LOL Seems odd that she works for the company, but never bothered to get on their email list.
You sign up to their email newsletter and you get invited to a sale (if you get the email, as it seems some didn't). There has only been one sale so far (I think).
