When you purchase an extension on boostmyshop.com, you can download extension source code and use it as long as you want.
However, the license (that includes support through our ticket system and new release download) is limited for the subscription period you select on purchase (3 months, 6 months etc...).
Once the license is expired, you can continue to use the extensions but you dont get access to support or releases download.
If you want to extend your license for 1 additional year, it costs 50% of the extension price.

One license is valid for ONE magento installation, even if you have multiple website on the same magento instance
If you use several Magento instance, your need one license per server.
Each license also include a development server on which you can do your tests.
