Namebox is a simple service to list unwanted domains you may have and want to sell. The service is free to use and simple to signup. The service also offers a pro version that you can list up to 120 domains and keywords for $29 per year.
The service is easy to use and I was able to list an unwanted domain in about 30 seconds. If you are looking for a way to get rid of domains you lost interest in then Namebox is the answer. Check out Namebox HERE
