Domain registrars do have "pools of cash" because so many people are willing to waste money registering these types of domains. Don't let them count your money and smile running all the way to the bank. Ring them up and DEMAND a refund.
Grace delete makes them utter GD under their breath because they know you know that they know. IMO.
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.
