Pricing a Parked Domain Name? Why not selling?

[DomainMart]

“Consider that a parked page like [xyz.com], for example, captures 15,000 monthly targeted visitors. Purchasing this volume of traffic through a pay-per-click search engine would cost nearly $10,000 per month (based on the current top Yahoo bid price of $0.66 for the term "[xyz]"). Yet we have the domain name currently listed for sale at domain marketplace [zzz.com] with an asking price of $350,000—an investment that would pay for itself in under three years—even faster if current trends of rising traffic and click prices continue.”

The above is a quotation regarding a domain name (generic four-character), but I have disguised the domain name and the listing site.

Why isn’t this domain selling?

It's all a matter of finding the right buyer -- liquidity is up, but domains still remain a specialized market: try professionally contacting end-users and you may find yourself with a nice deal.

Thanks!

Is the valuation math correct?
