Plus if your 200-day typein traffic figure is accurate, that's over 70,000 visitors a year that the new owner will get just by owning the domain name. Even if you lower the figure because of winter (but there's winter sports etc.) to just half that, over a decade that's 300,000+ visitors or just 10p per visitor. And that's a fraction of the PPC bids on sunglasses-related terms, not to mention that this doesn't factor in ANY non-typein visitors at all!
