I would have sold it for $20 if given the chance, just becasue there are lots of Wii domains out there doesnt make it ok and doesnt mean they arent aware of the domains in question. You may just be in Nintendo's "lawsuit queue"
Disclaimer: Please keep in mind that this is a FREE appraisal. This is a guess at quick flip resale value not an unrealistic end-user price. Often times my appraisals are rushed, too low, or too high. Sometimes my advice is totally wrong and occasionally downright dumb. If the post stamp is after 5:00pm EST, the chances are even greater that inaccuracies will occur due to blood alcohol levels.
