MYDUE.COM is on sale from BUYDOMAINS.COM. Premium Domains will accept any price listed by BUYDOMAINS. BUYDOMAINS.COM sets their own price and then syndicates them to all DOMAIN marketplaces (in bulk). Many times, BUYDOMAINS picks a number that is reasonable, sometimes they pick a number that is not reasonable. Until the domain sells, just because someone at BUYDOMAINS picked that number really means nothing.
As a point of reference, I purchased AGENTS.NET from BUYDOMAINS.COM in 2005 for $2,500. Now if Agents.net is worth $2,500 - then most .NETs are worthless - which is also not true. Most of my purchases from them .net have been in the $500-$1000 range (bathroomremodeling.net, fitnesstrainers.net, etc) for domains tied to medium level search terms - which is missing on this appraisal.
After I purchased it, I got massive flack that the domain was under priced. They accepted the sale, but not without alot of grief. Trust me, I've bought many domains from them. They are all over the map and rarely price their domains at market conditions.
Still, the true value of domain is based on sales, not sale prices.
You have to have faith in your reg - otherwise why reg it. But in this case, it is our opinion that the reg is low values. Doesn't mean either of us are right.
