In our store, "Government" is a broad term referring to non-profit organizations, which might include a school, a department within a university, a not-for-profit research organization, or possibly a state department or ministry of education.


The price of a single license is $78.


If you're unsure as to whether or not your outfit is what we call "Government", or if it's what we refer to as "Commercial", please send us a note with a link to your website and we'll check you out.
