if it's actually "substandard" then it means it's not a copy of the original because there is no original to copy. meaning they were selling the latest seasons of the shows which aren't on sale yet.
Well, no, it just means it was substandard. The DVD itself can be poorly written, and might not play properly. Box sets might be missing items.
There was no indication in the article that they were selling the very latest episodes.
if you want the latest season of game of thrones, you are going to have to wait until 2014.
the industry needs to learn that when there is a demand, someone will fill it. if you aren't filling that demand, someone else will.
Do you mean, when there is a demand for cheaper product? There was no indication that these DVDs weren't available anywhere else. But most likely they were cheaper than the product that is available in the store.
