Costco Wholesale Corp.

Retailers’ increasing success with own-brand products is forcing national brands to address their dwindling competitive advantages

Costco and Coca-Cola Co. staged an “end zone worthy” promotion to offer shoppers a voucher for one free pizza from the warehouse chain’s food court with purchase of three 12-ounce 12-packs of Coca-Cola products.

As I proceeded through the electronics area, I saw an elegant appliance island on the main aisle – with an array of kitchen and laundry appliances featuring LG, GE and Samsung.
