I found the blister twinpacks today and bought a bunch, it only took me about 5 or 6 packs to pull the 3 different cards (Yoda, Clone, Grievous).

Not a bad deal, 3.99 for a pair of packs and you get the bonus card as well so I like the bonus aspect of it.

I sure would hate to buy a bunch of these and somehow not pull all 3, though.
