Twinner Iberia continues to federate other smaller Spanish buying groups around it in order to raise their collective buying power. It has signed a collaboration agreement with Gys Sport in the financial, administrative and commercial areas, starting with orders placed with some strategic vendors by their retail members for the autumn-winter 2015/16 season. Founded near Bilbao in 1998, Gys Sport has 29 members with 40 stores in the northern part of Spain. Twinner Iberia, whose members manage more than 350 stores, had previously signed similar agreements with two other similar cooperatives, Grup Balear and Giro 180.
