Can a Red answer me about the Snowdown Shop ?

"We’re also unveiling Your Snowdown Shop, an in-client destination outfitted with discounted Champs and Skins unique to you." Could someone care to explain ? I mean ok so champions and skins are going to in the shop, duh , but which ones ? My top played champions and their skins ? Champions that have a similar playstyle to my top Mastery champs ?
