I found Treachery at Saleucami at Wal-Mart this last week but somebody had replaced one of the troopers with a Mace Windu! They even replaced the weapons with Mace's lightsaber and returned it. I brought it to customer service and reported it as a theft item.
If you're reading this you thief -I'm on to you!
decadentdave, I've seen those 2 figures a few times. I'll keep an eye out for them for ya.
