BBMC belongs to—and is governed by—its members. ANYONE CAN JOIN! You don't have to be a member to shop at the Co-op, but members enjoy lower prices and other benefits.

In general, BBMC sells products represented by the following categories: window repair, kitchen and bath, windows and doors, storm products, weatherization, and green products.
