Amazon is selling the soon-to-be-released box set of the first 4 seasons of Buffy for only $120 right now.
You can also pre-order the 5th season...
Oh, and since I'm copping to my geekness and sitting here watching the Special Edition of the Fellowship of the Ring we shouldn't forget that the Two Towers Special Edition is coming out fairly soon.
The former was really a far superior movie to the one released in theaters. I'm hoping it's true of the Two Towers, too.
