OPL - MICROSOFT OPEN LICENSE PROGRAM
Microsoft Open License is a software volume licensing program designed for corporate, government, charity, and academic customers who order as few as five licenses. After the initial order, customers can benefit from volume pricing for all licenses for the remainder of the term of their Open License authorization number.

With Open License Volume you can potentially save a lot if your organization is able to make a large initial up-front order in one or more product pools (applications, systems, servers).
