So this Snowdown Shop

To be honest I really excited about this. Expectations, however, are not reality. I know, I know, it's luck of the draw. But is my luck really so bad that I got a sale for two Skarner skins (I'd like Earthrune, but got two others), a Kog skin (when I already own THREE Kog skins), two Gangplank (I'm not sure I've ever even played him; why give me two)?

I'm not asking for anything, I just think in the future it would be nice if whatever algorithm was used were a bit smarter.
