I wonder if that price is a typo - or if the seller is hoping a high price will fool someone into thinking it is worth having.
I've seen some stuff go on eBay for considerably more than you can buy it brand spanking new.
In fact there was an out of print boxed set for a musician who had a cult following but never mainstream following - it was out of print for several years but BMGMusic club still had many copies of the boxed set in stock. I was buying them and selling them at double until some other sellers saw what it was going for and then the market was flooded with them.
Sometimes people are too trusting in the value the seller places on an item, and it only takes one sucker to make a nice buck.
I suspect it is a typo though. Seller meant $20 or something.
