I will be shutting down my demonstration Drupal E-Commerce web site, wwdbooks.com. This site was not getting any traffic. It has become an unnecessary expense. I will do my Search Engine Optimization research using my playwriting web site at http://robertsrobbins.com/. I have backed up the web site and its MySQL database.
There does not seem to be much demand for custom E-Commerce web sites. I think most people sell merchandise on Amazon, eBay, or they use hosted E-Commerce web sites.
