Just picked up a few 5-Packs of these at Target tonight. I was intrigued because the cases are identical to the one included with the Lava Vader figure with one shortcoming: the background image of Vader's helmet in the fiery lava (like the Lava Vader figure) is only one per pack. Why they didn't include one for each case is frustrating. Also, they are $9.99 for each 5-pack. They are seriously overpriced. For ten bucks I should get 10 cases... it's that simple. And the cases do nmot fit very well over the Revenge of the Sith blister cards very well, in fact, the cardboard peg hook will easily get bent inside of the case as happened to my Lava Vader figure.
I applaud Hasbro for making these avalailable to collectors but it kind of missed the mark. My advice: Wait for clearance. I'm sure these will be marked down to $1.94 within 3 months.
