I've been going out hunting for late 70's to early 2000's VHS sci-fi and horror movies at all the local Half Price Books lately, if that counts. I was pretty stoked to have picked up nice condition copies of 2001: A Space Odyssey and The Matrix for $1 each a few days ago. =)
I do and yes, lots of great deals to be had when it comes to CD's especially. Almost always see CD's priced at $.25-$.50 at garage sales. DVD's usually a buck. They're much more expensive at GoodWill and Salvation Army these days!
