I've seen a few people saying they didn't receive the Launch Event Kit. Here's the question: Did your store actually order it?
There were two events to sanction. The first was the actual Encounters season (running for the next 13 weeks or so), the other was the Launch Event Kit. The store also needed to separately order copies of the adventure (as they're regular product).
If your store did all of those things, you should have:
* The Launch Event kit - expanded first encounter adventure and poster map.
* The Encounters kit - notes for using the adventure in Encounters, 20 dice and two sets of 10 NPC cards
* The "Legacy of the Crystal Shard" adventure
In our case, the Launch Event kit arrived a few hours before the event (and almost arrived afterwards), but it was sent.
