Given how only one Wal-Mart near me has gotten anything past the Episode I wave, I broke down and ordered the case with Wedge in it from BBTS a few minutes ago. I'm going to wind up with a few figures I don't need (Maul, Qui-Gon, and Nom Anor), but I'd rather pay for 9 figures I do want/need now than have to worry about searching later. I guess (unless the case never actually ships and I don't wind up with the figures at all; what a pessimist I have become) that only leaves me needing Bespin Han and Barriss Offee (from wave 7) and Darth Malgus and the Imperial Navy Commander (from wave 3) to be (technically) "caught up."
Only the second case I've ever bought online, btw (the first was the AOTC wave last year which, Hasbro should take note, I only ordered because I needed 10 of the 12 figures from it; this is why even halfway acceptable case packs are better).
