The domain makes very little sense overall. For a brief second I thought you posted - Wholesale.com - but clearly thats not the case. If you get traffic because of a possible typo - there would definetly be some value, but as it stands - Im not seeing much. Primarily because Whale Sale even if you market it as a "Large" sale - doesn't quite make sense and isn't very popular.
To me, this is a reg fee domain name.
