If you haven't checked yet, Load up Overwatch and you'l get 5 Winter boxes from the developers for FREE.
So don't waste, go get those duplicates! (Fortunately for me, I got the Nutcracker skin!)
i didn't get any dupes but i only got sprays/voice lines lmao. the only good thing from those was the widow highlight, i'm very tempted to buy lootboxes before the event ends, i have all the legendaries but santaclad which i really want >_<
