Well, it's an odd deal to be sure. While it's true that Walgreen's does split up cases among stores, the ONLY figure to have shown up so far is Glenn, and always in a pair or pairs. This is how the exclusive Rick showed up at first too, and then later they got a larger selection at each store. But Glenn is not an exclusive figure so hard to say why he is the only one shipping so far.
I do expect the others will show up before too long.
Greg, that's a bummer to hear about the 10" Daryll. I still have mine in the package and constantly debate opening him. Maybe he is better off where he is though.
