If you didn't hop on this offer after it was put back in stock the second time, you're not out of luck again! No word on when this item will return, but let's cross our fingers and hope for another shot later this year. Thanks to Travis for the heads up!
I got one of those cases the first time they became available. I didn't really need it when I got it so I sold it on eBay. They are worth quite a bit! I was able to get $35 for it several months ago.. XD
