VIDEO : Costco's Kirkland Is Worth Over $75 Billion

According to Business Insider Costco's Kirkland Signature brand is one of the company's biggest assets.
Kirkland accounts for nearly a third of it sales.
A recent report from UBS says Kirkland could be worth around $75 billion.
The analysts estimate is around $15 billion more than Estee Lauder, for example.
The Kirkland private label also helps to drive down prices for other brands at the store, as these brands must position themselves to compete.
