Query: Duplicate of Season 3

I would not have ordered this DVD if I had realized it was a duplicate of the Season 3 I already own on Amazon Instant Video. It would be helpful if customers could see a description of the episodes covered in a DVD before opening the packaging, as I did, thus rendering the DVD non-returnable. Love the series, but I would rather have spent the money purchasing Season 4, which I did not already own.
