if you bought a season pass of a show impacted by the writers strike, there is still no resolution on how apple is handling those.
I have a season pass for How I met your mother, and was going to get the one for the Big Bang Theory, however since the strike continues, and contrary to a previous poster's comment, neither show has any new episodes remaining in the can I opted to not buy another pass yet, since I still have no idea what they are going to do about my existing and unfulfilled pass.
I suspect a refund/credit will be issued once the strike is settled, or once it's clear there definetly won't be anymore episodes this season. But per the mac support person who emailed me yesterday to update my inquiry, there has been no decision to date on what to do. I think for now, it's a wait-and-see about if the strike will be resolved and the remaining episodes made, or not. I'd guess if you complained enough now, you'd get a refund. Me, I am still hoping to see what I paid for...
