Why are there so many Pink Mercys?

i feel stupid asking this but i’ve been seeing so many of those breastcancer awareness skins lately, was that in the shop and i missed it?

(i can see nobody understood this question Lol)

(i am talking about how pink mercy hasn’t been in the shop for a super long while to my knowledge, it has been known as a skin only people who played forever ago got. but now i’m seeing a random bunch after starting to play again. did it reappear in the shop?)
