Cooperative Purchasing

The Greater Portland Council of Governments’ (GPCOG) Cooperative Purchasing program saves our municipalities thousands of dollars every year. We coordinate a competitive bidding process for the purchase of a wide variety of vendor products and services to obtain the best possible pricing for our municipalities.

In Fiscal Year 2019, we saved our member municipalities more than $365,500 in road salt purchases alone.
