Wicked Coaster Giveaway

I received a push notification today from xFinity saying that select stores would be giving away a set of Wicked Coasters to the firs 100 guests. When I hit the notification, it took me to the "find a location" page but then I was unable to find anything else in regard to the promotion, or if any of the stores listed were giving them away. Did I hallucinate this? I don't know how to see previous push notifications, since they disappear once you tap on them. Was there some kind of notification like this sent out? I see there is a Wicked fun pack download available as a reward, was the notification in regard to that and I misunderstood? I have tried every variation I can think of in the search enginge to find an answer but nothing is coming out.
