They really wanted to make sure they don't "lose money" from My shop, did they?

I don't know whose shop the one which popped up for me is, but it surely isn't mine. Let me give you all a quick overview of what i got:

70% off an Ezreal skin. The biggest discount wasted on a champion I NEVER EVER played. I don't even have him unlocked.

60% off a Lux skin. Just like Ezreal, never touched this champion.

70% off an Elise skin, a champion I played 2 games with 2 months ago.

50% off an Akali skin, same situation as with Elise.

The only champion which i actually play between those who appeared (Syndra and Pantehon) weirdly got the lowest discounts (20% and 30% respectively). Wasn't the My shop supposed to be tailored to each player? Cause surely mine wasn't. Or, to be more honest with ourselves, it was made perfectly so that they wouldn't "lose money" from me buying a discounted skin. Worst case scenario for them is that I spend 300 rp less than what a skin usually costs. Cause let's be real, do they expect me to spend money to get a skin for a champion I DON'T EVEN HAVE UNLOCKED??

Am i the only one who got an absurd shop? Or is this a widespread issue?
