These are to replace poor quality black market versions of the exact same things.

"Salo, or the 120 Days of Sodom - Criterion Collection"
This arrived today and I am amazed that the english dubbed version isn't shitty.

"Cannibal Holocaust - Limited 2 Disc Uncut Edition" I've seen this a billion times but the copy I own is a cheap bootleg.

"Kill Whitey" -- Flesh Parade. Great album and it's time to give my downloaded mp3s a rest and hear a high quality version.
