What's the difference between LEGO Star Wars: The Complete Saga and LEGO Star Wars III: The Clone Wars?

I can't wait for the LEGO sale, I feel like a little kid again! But this is only if they are 800 MSP ($10.) If they are 1200 MSP ($15) then I will cry and not buy any of them.

I'm also definitely going to get Sonic Adventure 2. If Toy Story 3 is 800 MSP then I will get that also. I've never played The Walking Dead, but obviously I'm going to get the game for free and if I like it, I will get the other episodes, which will probably be 200 MSP each.
