In the wild or on Ebay/Amazon.
I find it interesting on various message boards and social media sites that some folks refuse to pay $10 for any tape (hilarious given the rarity/value of some of the tapes we discuss here), and think no tapes are worth more than $10.
Given that, what was the most you have ever paid for a VHS tape?
For me, it would be $40 for the 1991 WCW Halloween Havoc PPV on Ebay. Its one of the rarer wrestling tapes, plus the Halloween Havoc tapes seem to be more collectible for some reason.
