a lvl 11 account, have been waiting for this my shop since last one to make sure it's intentional, why? EDIT: I completely didn't notice that it could be the champion's price added to the skin price, so I am sorry for assuming that you were trying to trick the players, my sincere apologies.
Lemme guess, you don't actually own the champions so they added the price of buying them outright with RP. But because you played them during free week they show up in your shop because at that level the algorithm has little to work with.
Maybe it's just a bug?
Why do you assume Riot is lying maliciously and trying to trick you?
Escheton is probably right, if you don't own the champions then their RP cost is added into the skin. Maybe Riot mistakenly left free week champions in the algorithm. I doubt it was intentional, lying, or a trick.
