"Ain't It Cool News" DVD listings
These listings of DVDs appear frequently on this site, and I suspect they get some kickback from linking to Amazon through them, but considering the amount of cash these heads-up on price changes have saved me over the past year or so, more power to them.
70 percent price cuts are not unknown, and half-off is common. I'm glad someone is collecting the bargains on one site.
Firefly, the complete series: Thirty bucks! The complete Prisoner: 70 bucks!
