Returned my extra copy to Best Buy no problem, but the store I was at had something new to me. There were no 4k copies of any movie on the shelves. Instead, there were tags that basically said to see the front counter (or associate) to purchase 4k movies and steelbooks. I thought the cases were frustrating enough. However, if this means that do not have to put any in cases, thus limiting damage, then this may be a pretty smart idea!
(I just hope they wouldn't mind somebody like me inspecting each copy before buying haha).
