The TV deal of the week over at Amazon this week is Buffy the Vampire Slayer – The Complete Series DVD for only $70.99 (that’s 65% off the list price of $199.99).

Note, this deal is valid through Saturday, October 23, 2010 while supplies last.

This DVD box set contains all 7 seasons of the popular Joss Whedon television series which starred Sarah Michelle Gellar as the titular vampire slayer along with Alyson Hannigan, Anthony Stewart Head, and Nicholas Brendon. Buffy the Vampire Slayer, which ran from 1997 to 2003, also co-starred Eliza Dushku, Seth Green, James Marsters, and many more, as well as introduced the character of Angel (David Boreanaz), who eventually got his own spin-off show.

Math time: at $70.99, you’d be paying only $10.14 per season! That’s a steal, considering the box set is worth getting even at the original price.

This 39-disc collection comes with the following bonus features:

– Introduction by Joss Whedon
– Back to the Hellmouth: A Conversation with Creators and Cast
– Breaking Barriers: It’s Not a Chick Fight Thing
– Love Bites: Relationships in the Buffyverse
– Evil Fiends
– Buffy: An Unlikely Role Model
– Buffy Cast and Crew: Favorite Episodes
