That's one way of doing it, but it's not something we can officially support. Right now, Seasons 1 through 16 and 20 can be purchased on DVD, with 1, 13-16 and 20 on Blu-Ray. iTunes has seasons 1-3 and 20-25. It's not going to be until December 2016 before seasons 17-19 are available to purchase due to whatever contract Fox has in place that says "we won't release a season until 9 years after it ends", which is way out of date for the marketplace.
