Costco has begun replacing Pepsi with Coca-Cola at its food courts this month, aligning with its January plan to make the switch.
Coca-Cola confirmed the rollout is happening at all Costco warehouses and will be complete by fall.
Costco Canada has already added Coca-Cola products, announcing the update on social media.
The retailer had previously swapped Coca-Cola for Pepsi in 2013 to keep its famous $1.50 hot dog combo price steady.
Costco currently operates 908 warehouses globally, including 625 in the US, and plans to open seven more in August.
