When you buy or receive a Legendary or Ultimate skin this Snowdown........

I bought a lot of skins this snowdown. I think that it's shady to have writing like "When you buy or receive a Legendary or Ultimate skin this Snowdown" and have it be for a specific part of an event. **When you buy or receive a Legendary or Ultimate skin this Snowdown **you’ll unlock a free Mystery skin! If that Mystery skin happens to be a Legendary or Ultimate, it unlocks another Mystery skin and can continue to snowball from there. As an added bonus, we’re doubling your chance to unlock a Legendary when you receive each Legendary Snowball Mystery skin.

I just think that if people bought legendary skins at any point this snowdown they should also be given a mystery skin. I work in Business and this is poorly worded and would have customers upset.

I just want some price protection of some kind. I bought: omega squad teemo battlecast Skarner Primetime Draven Firefighter tristana
