I miss this show and had to buy the complete season. Not happy with the way it's laid out but hey at least i have all the episodes and some extras as well. The lay out is a little tricky but at least everything is there and for a great price.
I love this set!! The extra videos are awesome!!
This is sold like a separate season, a single season.... therefore when you buy you own just a box set not seasons 1-12 but a single season of all episodes. This is told to me by Apple that is what they did.... therefore if you buy this and then go to search in their new Apple TV app for the Big Bang theory any season and any episode (expecting to be able to watch ANY as you bought all the seasons right?!?, wrong!!!! It shows like you don’t own any of it, why because you don’t own each individual season but a separate season made by them as an alternate season one which has all episodes assigned but does not connect or correlate with the rest of the iTunes system. Horrible!! I feel cheated!!! Lied to and unable to fully enjoy my purchase!!! Any other streaming eg. VUDU does not due this as bundles include each individual items within the bundle, iTunes does not!!! Would have went through VUDU instead had I known as this was my first iTunes tv box set purchase... never again Apple.
Appreciate getting the complete set plus some extras for 50% off!
The original price was $199, on sale now for $99
iTunes Store advertised a 50% off sale on the Complete Series of The Big Bang Theory. It was originally $119.99, but instead the price was $99.99.
Such an amazing tv show with a very good deal!
I love this show, it’s my all time favorite comedy
