Mystery Gifting per-Stage: Ward Skin Reward?

As a part of the introduction to the "Welcome to the Worlds Shop" post Riot sent out as Worlds began to hype up, they said that if you sent a mystery gift during each stage of the Worlds, you'd get the 2015 Championship ward "totally free." When can we expect to get these? I'm getting kinda uneasy that I haven't received mine yet as the Worlds Shop closes on November 5th (Thursday). Anyone know? Thanks
