They usually just send CC from a particular collection to you once. I want to stress the word "usually." They sent Wanderlust collection polishes to some people who had marked nail polish as a just-can't-get-enough (great, now I want to break out the Depeche Mode) in two consecutive months. Different colors, but I had already swapped for the one they sent me the second month, so that was doubly frustrating. But if you received something from Harlem Nights, that absolutely does not have anything to do with whether you'll get something from Gala's Gems.
