gruv.com which is sort of like the late WBshop for Universal media has the set for $54.99 with free shipping .
I have read others have ordered from them without a problem. I personally have not ordered...
Based on limited examples, I am guessing Universal considers 4 films in 4K box set to be the way to go as both this set and the Hitchcock set were both 4 film sets while they are only a few of the possible films that could have been included ie 30 for Universal Horror and 14 for the Universal...
I love these films but I can't justify buying them again. I settle for the 30 film blu ray set I have.
I agree its odd not to include "The Bride of Frankenstein". "Frankenstein" and "Bride" are one story.
