These modules are designed to add additional functionality to your Zen Cart website. The modules listed in the section are available from zencart.com. I do no pretend to have authored these (unless so stated in the description - which, authorship can be verified by visiting zencart.com and viewing the author information for the module). Therefore, I am NOT selling the module, but merely the installation of the module to your zencart. If you have any questions or concerns, please feel free to contact me.
