Not sure what your point is. I had a look at the two CDs you listed and they are both still for sale, and I would think, over- priced.  Good luck if he/she does sell them for the asking price.

The GANGgajang CD may have sold for that price a few years ago, but like most CDs, there is an oversupply on eBay and little demand (and other eBay seller has the same GANGgajang CD for $7.00 less)
