Bought these already, but in sets of two at a time before they released the full boxed set. Thankfully, we really didn't pay more all total, because I got pre-order discounts from the website I ordered from. And they are the same DVDs as we got in the paired sets.
I highly recommend these to Python fans. The extra footage, background information, trivia, Gillianimations, etc. are more than worth the cost.
