4k's are $29.99-34.99 standard price here.Here WB catalog titles are always $29.99. And they never seem to go down in price (Goodfellas and Mad Max Fury Road still are).
Only exception was Wonder Woman for a bit after it came out and a one week sale on some of the Nolan titles.
Pisses me off.
I haven't seen them but I have heard the Bourne movies are the most subpar titles on UHD according to the bluyray.com members
I think I've got around 30 4k's now.
