I love Arbonne Cosmetics. I'm an Arbonne Consultant to I have access to them all the time. They aren't sold in stores, you can only order them through a consultant. They are available to order online, you just need a login code.
I LOVE their primer. I've tried dozens of other primers. I've used MAC's I've used Makeup For Ever's and a bunch of others, but none of them had the same effect. Arbonne's primer is silky smooth. It feels like you haven't even put anything on. Other brands I've tried feel water-y, or they seem to bring out redness on my face.
I also love their eyeshadows. They don't have a huge selection color wise as their products are all natural so unless you find an electric blue colored plant somewhere in the world, chances are, they won't have that color. But as far as the basics go, brilliant.
They also have a lash enhancer that is similar to Latisse but without the weird side effects.
