UPDATE (5/2/13): The Host DVD will be released July 9, 2013.
You can now pre-order The Host on DVD and Blu-Ray on Amazon in the US. The DVD is listed at $19.99 and the Blu-Ray is $24.99. If you order now and the prices go down, you will be charged the lowest amount. However, there is no release date yet! But if you want to be one of the first to own a personal copy, I guess the time to do it is now. We will keep you posted on a release date or any details on the actual DVD when it becomes available.
It is not available on Barnes and Noble, Walmart, or Target yet.
Thanks to our twitter follower @MoreNayi for the heads up!
