Series 2 is beginning to ship to some Targets. Characters in this set include: Boba Fett, Darth Maul, Gamorrean Guard, and C-3PO, and others shown above. Not all characters come in each case...so hunting may be required.
They got some of these (along with characters from lots of other franchises) in the branches of the gaming stores Electronics Boutique, but they quite expensive. The same stores also have some other unique-to-them merchandise - I once saw a Star Wars Lava Lamp there.
