I am so glad I started preordering sets online back with wave 3. With the spotty distribution of Wave 2, I saw the writing on the wall even then. If I had relied on retail, wave 4 is the last complete set I would have. Waves 5, 6, 8, and 9 never showed up at any store in this city, and we only got one case assortment of Wave 7. Thank Grodd I was one of the lucky few who actually received their wave 9 preorder. Just need to snag a comic Mantis (my preferred version) and I'm set.
