Just stick with us Hemish, and we'll find ya' some good deals! How "completist" are you? You gonna need all the carded and super HTF Chase figures too? Or just the basic figures?
Unfortunately, you've gotten yourself off to a rather precarious start with that eclectic lot of Kubricks you bought. They usually sell these things by Series/wave, but you managed to mix a little of each series together there. So now you're gonna have to do it the hard way, and get the rest individually most likely...

But we'll do what we can to point out some good deals to you. You should know off the bat that the Early Bird set with the only Luke, Leia, Chewy and R2, always sells as a set, and never below $125.

So best to get you goin' on the rest of the Bounty Hunters and Series 2 (ANH).
But once you've gone Kubrick, you can never go back...
