Costco's competitive edge lies in its tight cost structure; by combining bulk buying with low markups, the wholesale strategy becomes a win for both Costco and its members. Its private-label brand Kirkland Signature accounts for about one-third of Costco's total sales, providing margin control and customer loyalty. Costco has gained traction with younger customers who are signing up for memberships.
