I love most Shu products. I used MAC for years and I have to disagree with some of the previous posters. Shu is much softer in texture, blends easily, is more pigmented and lasts longer. I find MAC e/s to be very chalky.
The blushes are really pigmented and last all day. And the quality of the brushes are fantastic.
If you look on their US site, they list all of their retail locations.
