Found all these Pride DVDs in a bargain bin at a big box store. $5-10 each. Will be getting many more as they had about 40 individual DVDs. pic.twitter.com/WC87kPhj 
Good stuff that's an awesome find. 
Posting blind for OP:
Lockerroom Fever is my personal favourite. 10/10 sir. But seriously who needs 151 when you have this collection. Pride FC 1-5, Shockwave 2003-2006, Championship Chaos II, Cold Fury 3, Openweight GP 2006.
Where did you find such a collection?
For Canadians I found tons of 'Pride Fighting' DVDs @ Zellers. $4.99 for single events and $9.99 for box sets, dropped about $100 and am just getting ready to watch Shockwave 2004 with a bud who hasn't seen it. No homo.
If you're new to the sport they also have boxset seasons of TUF for $9.99. Homo.
Went out and got more from the bargain bin, including the 2000 GP pic.twitter.com/rys6Dait. To anyone in Canada you should really get to your local Zellers. Each of these have been either $4.99 or $9.99
god dammit our zellers closed down like 10 years ago
edit: no wait that was kmart!!!
I got Pride 1-5 boxset= 5.99
Pride 23 = 2.99
UFC 48= 2.99
THEY HAVE A TON MORE TOO
