You know, about a week or two ago, our local Wal-Mart had a huge endcap full of ROTS pez dispensers, and the next time we were there, it was gone. All I have seen since then are a couple C-3POs in the smaller, register display (alongside Batman, Donald Duck, and other PEZ dispensers). I did get a chance to pick up the Glow in the Dark Emperor, and it does say "Wal-Mart Exclusive" on the packaging. The ones I have seen (and picked up) so far are:
GITD Emperor (WM Exclusive)
Regular Emperor - missed this one, red robe
Boba Fett - reissue likely, but I've never gotten it
Chewbacca - looks like a new sculpt to me
I've heard that Yoda and R2-D2 have been out there too, but I haven't seen them. I still need to get the R2 eventually. They are still sitting in package in a closet right now, haven't decided how to display them. Do any of you display your collections? I was thinking about opening them up and putting them together that way. Something "different" to have as part of a collection, I suppose. I could be wrong, as I didn't look close, but I could have sworn I saw those large scale PEZ dispensers at TRU yesterday. Maybe I'm just dreaming that up or something.
