Well, the one time our store has gotten the Coruscant wave it was half-full of UGHs but I was actually happy to see most of them because I was looking for repacks- ironically I was (and still am) looking for a Boba Fett, but the store was alack for one.
I'd say these didn't sell out too quickly since I went mid-afternoon, but in a small city and for all the figures to be gone in a couple days.... I mean, the Hoth Wave stuck around for ages and Derlin is still pegwarming at that.
I actually bought a UGH Vader, but I've traded him to another forum member for two figures I was looking for, so good deal there IMO. You might consider doing that.
...actually, I'd buy that Fett off you at store price if he's still hanging in your store for some reason... and I'd definately be willing to pay shipping and such.
