TRU and Wm around here have tons of them Anthony... Target only seemingly got them in once, only prequal ones too, and only at the end of the holidays... And it seems like one case or so per store too, not much. Kind of sucks really.
WM's though around here have TONS of them depending on where you go. My nearest has maybe a dozen ESB/ROTJ sets (nothing else save for cantina exclusives), yet the first WM on my larger toy loop I make sometimes has I'd say 36 to 50 tins, mostly Original Trilogy and Cantina, with a smattering of PT sets here and there... Not much beyond that, but it's a lot of what they do have.
The PT sets are the ones that moved though... Even KM's $32+ price on the PT sets (KM was the one store I saw PT sets in some abundance) went faster than the OT sets. I mean, even that rape-ish price they sold really well over the holidays. I think since the OT sets are in abundance at TRU and WM alike they are sitting... TRU has probably 3 full OT sets at any given TRU I visit.
