The list author says: "This is all of 'em in order to make it easier instead of having to search for each one specifically.
A lot of these volumes have 2 versions. I'm sure there's no difference but do a search for you want to buy 'cause some will be $22.98 lowest price new but the other version can be bought used for maybe $7 or $8 cheaper used.
Added mostly the $22.98 new price ones just in case the used ones sell out and then it'd look kinda stupid since that one might be $42 new then like some of these are.
DEFINITELY CHECK THE TWO VERSIONS OF EACH CD VOLUME TO SEE WHICH IS CHEAPER!!
Enjoy. And by the way... I LOVE THIS WHOLE SERIES!!! Buy 'em if you like rockabilly, rock, old tunes, instrumentals, instruments, classic sounds, real wild craziness, etc. Or maybe for just the cool artwork?
You really can go wrong here with any of these volumes.
I don't own them all but I'd sure love to if the price was right (lower, haha).
