Existing reviews of this set are of the "season's too short" or "price too high" variety. While both of these opinions are valid, you need to take a few things into consideration. Season 4 of My Boys was wildly unsuccessful in the ratings, TBS buried the show in a terrible time slot, and the season, like seasons 2 & 3, only consisted of 9 episodes. We're lucky it was even printed to dvd.
The reason the price is so high is that this is a "series on demand" product from Sony. They haven't mass produced hundreds of thousands of copies of this series to ship to stores or ship to warehouses. From what they say, the set is made in small batches when ordered. You order it, they make it. That's pretty cool.
I, for one, am grateful that this season is even available to purchase in a physical form, allowing the discs to sit on my shelves on dvds to the first 3 seasons of this great series. And I was happy to pay the extra $10 to do so.
