The co-op that I am active in does several things, not necessarily in this order:

* We reduce the price of medicine to our members.
* We give money to qualified organizations with LOCAL ties (Salvation Army, Food Pantry, Battered Womens Shelter, etc.)
* We increase what we pay out to our growers.
* We take on more people who have LEGITIMATE need for free medicine (usually thru referral from doctor or hospice).
