Good Lord, $70?? I wouldn't think so if it was me. I think Sephora or Ulta carry that brand. (Can't remember which.) If you live anywhere near them I think it would be more cost effective to go in and take a look at the products and only buy the items you want or need from there.

If you're not married to the idea of that brand in particular, there are also lots of other smaller mineral companies online whose products are more inexpensive and that are just as good, if not higher quality - and have more extensive shade ranges. Meow, Lumiere, Aromaleigh, and Dreamworld come to mind that I've tried, though there are others, too. And they all usually offer small, relatively cheap samples to actually try a few times IRL, something I think is always a plus.
