In its first week of sales, the Canyon County Co-op sold more than 100 memberships, a third of the way to its goal of selling 300 by the spring, said founding member Sarah Nelson. A group of residents and downtown business owners came together to bring the co-op to Nampa after the Boise Co-op announced in July that it will open its second location in Meridian, despite Nampa’s efforts to bring it farther west. The new co-op will be the fourth in Idaho, according to the Cooperative Grocer Network, along with the Boise Co-op, Pocatello Co-op and Moscow Co-op. The 4,935-square-foot store will be at 1415 First St. S., a building now occupied by Snake River Crossfit, which is moving to a new location in Nampa. It is scheduled to open this summer.
