All of the more recent waves have popped in and out on wm.com. It's weird.
Did, regarding auto stuff, that's generally a regional thing. It's why one will have a huge hunting sportsman area another is barely anything. The auto stuff depends on the area too, generally. Toys I'm told is a much more generalized thing and thus it's more hit and miss. Walmart is odd.
It seems like the Scarrif wave never, or barely, made it past the Mississippi because the East got shafted while I know guys in the west who had entire endcaps filled with the wave and wound up with piles of Cassian. I got Cassian on wm.com but the Trooper I never get a sniff of. I've never seen a Cassian on pegs, or even repacks to make me think he maybe showed up.
At the same time we got the repacks last year while a lot of folks didn't see the royal guard barely at all.
