We sell two types of licenses on Codecanyon.
You can read all about licenses here : http://codecanyon.net/licenses
Short story, REGULAR LICENSE – You can install the plugin on a single domain, not multiple.
If you wish to install on multiple websites you must purchase for each domain a regular license.
None of the licenses allow you to resell the Plugin. Developer license doesn’t exist.
The plugin is property of AA-Team, and we don’t allow reselling the plugin elsewhere. If you do try to resell the plugin elsewhere, legal measures will be taken, and according to law, you can be sued.
