Xmas sales

Just wanted to know if only i got really lame skin sales on snowdawnshop, atleast they are for me becouse i never play with those champs, and i kinda hoped that riot would take info from our accounts and give skin sales based on that info or atleast do something like giving us to choose one skin to give it like 50% off instead of random big sales :/ and i mean atleast i would spen money on rp to buy a skin with sale that i want instead of random skin for a champ i never play with.
