You can’t unless you form a small group like a non profit organization or a business. You can cheat the system legally going the NPO route as long as you find a way to fulfill legal requirements, but you need friends (it helps to know someone in law school too) and you have to do the legal paperwork and share all the cost. The price to do this will vary depending on where you live. The price for the volume license can vary a lot depending on where you get it from. Where your group is located effects this. In my local it is about $200-400 USD.

Your other alternative is the grey market. Its grey because it is legally ambiguous.
