WM, being the hit-or-miss store that it is, is not a good outlet for any exclusive to me... Sometimes you have the Cantina set situation where they were abundant, and other times you have the TIE Bomber situation where you may or may not see them ever... Or to make it more recent, the Twins sets (I saw them and even saw clearance, but I know I'm the exception, not the rule, when it came to those twins sets).
WM definitely isn't anything to go "WOO HOO!" over since having a WM around you doesn't mean you'll actually get the item(s) at your store, haha.
Believe me... As a collector of a toy line that ONLY WM carries (besides etailers), I can definitely say I'm never happy to hear WM has an exclusive, much less one that is a movie clone set that people will be going nuts to get, and some will want many of.
