The prices are pretty good, especially with the free shipping and no taxes.
Mystery Science Theater 3000, Vol. XVI (The Corpse Vanishes / Warrior of the Lost World / Santa Claus / Night of the Blood Beast) This is the one with the little Tom Servo figure; maybe Christmas tree decoration size. Four pretty decent episodes for $35.50, 45% off the $65 MSRP.
Almost as cheap is the Mystery Science Theater 3000, Vol. XVII (The Crawling Eye / The Beatniks / The Final Sacrifice / Blood Waters of Dr. Z) for $35. Well, actually, it’s a tiny bit cheaper, but the discount is only 42%, because the MSRP for this set is $60, not $65.
For about the same amount ($35.50), you can also pick up the The Mystery Science Theater 3000 Collection, Vol. 12 (The Rebel Set / Secret Agent Super Dragon / The Starfighters / Parts: The Clonus Horror).
