Personally, I wouldn't trust those websites. They seem to be from the same company, because if you scroll down to the bottom of the two pages, you'll see that they both have the same email address. The email address is spelled "Customerserice" instead of "Customerservice." The summary of the DVD set on both pages has nothing to do with the Legends TV series; it's just a description of what ordinary legends are. The DVD cover shown is the one from the Legends Season 1 set. One of the pages even has the wrong cast and director listed.
This all seems very fishy to me. If Legends Season 2 had an official DVD release, surely it would be available from well-known sources, and it would not be for "All Regions." I suspect that ordering from either of these sites would get you a bootleg DVD set at best, and it might even be risky for your payment information.
Just my two cents worth of caution!
