Lego Star Wars Limited Edition Sets. Sith infiltrator, etc.

[legofactory]

I've seen hoth rebel base for sale at toysrus for $79.99. They are usually quite rare at the stores and not for sale online. But what about the sith infiltrator??? It was a wal-mart exclusive in Canada before. But they banned lego early 2007 and now they got lego again. But i dont' see any sith infiltrators. I don't want to buy at lego cause you have to pay shipping.

WHERE IS the sith infiltrator?

Also, i have quite a few lego star wars sets for sale. Any interested? Let me know ! Trying to get rid of some of my LEGO®. Especially since I'm short for $ and i want the new clone wars theme lego.
