Thanks to her post: http://www.musingsofamuse.com/2010/11/stila-holiday-blockbuster-set-at-costco-for-20.html
I stopped by costco after work and found this hiding behind other Stila items!!! =D
It's made in China (and that's probably why it's so much cheaper..) and some people are saying that the quality is not up to par with Stila regular eyeshadows.
I will post reviews soon!
