I believe they retail for $5, but where I buy them it's $2.99 ($3.99 for blushes).
And really, the texture of both e/s and blush are great. Very fine textures, and pretty well-pigmented. There are different finishes, just like MAC.
But, they seem less like a MAC substitute and more like a Chanel substitute. They even have those little diamond-shaped things pressed into them. If that makes any sense.
Anyway, Nyx is good stuff. Excellent price, and very decent quality shadows and blushes. You can buy their stuff online at nyxcosmetics.com
