I was lucky enough to pull one (300+ SITS if wondering), but I agree, it wasn't even announced on Twitter, only people in game at the time knew about the shirt. It was a small enough window to begin with but to not announce it on any other medium aside from the game itself makes it that much harder. Not to mention all the people that were out doing stuff, I had gotten back home at around 930 EST from class and work. I'm sure a lot of people were out with their loved ones with it being Valentine's Day and all, plus all the people from Europe who are asleep, plus all the people who have other things to do and can't be on during this time.
