Bought Shaak Ti from this wave. The story how I got her is funny, really...
I had originally only bought Pre Viszla, because I saw him, and I've never seen him before in the wild. Other than that, there was also only the Ahsoka, Cad Bane, Odd Ball...etc. repack wave. I stumbled across a repack Asajj Ventress, and I wanted to buy her again, because I have the original blue/white-carded '08 release, and she can't hold her lightsabers AT ALL. It took me a while to finally decide I wouldn't spend the $6 (they were on sale) just for that tiny factor, and left the store.
Being that I was at the mall with lots of time to spare, I thought it over and finally decided to go back to buy it. When I walked in (about 20-30 minutes later), I found a fresh case of Wave 4, sans the astromech droid, on the shelves. There was only 1 case. I thought it was funny that Embo and the others had been untouched, but the astromech was gone. Either way, I immediately dumped the notion of buying another Asajj, and it took me at least 5 minutes to decide whether to get Shaak Ti or Embo. Eventually went with Shaak Ti, because I tend to lean towards Jedi characters.
