Scale creates an advantage
There is minimal risk that Costco will be disrupted anytime soon. Its massive scale is one important reason why. The previously mentioned revenue figure of $62 billion comes from an average of 4,000 stock-keeping units (SKUs) sold in the company's warehouses. This is much less than the 30,000 that a typical supermarket sells. Therefore, Costco sells a large volume of a limited number of goods.
This creates a powerful cost advantage. The company has negotiating leverage with its suppliers. This results in low costs that are always passed on to shoppers. These customers are happy, with memberships up 6.8% year over year in Q3 and a worldwide renewal rate of 90.2%.

Costco is a safe and reliable company that investors should always keep in mind. Even better, it continues to open new warehouses, pushing growth. Its ability to keep thriving despite the rise of e-commerce points to its strong competitive standing.
However, now is not a good time to buy shares. They currently trade at a price-to-earnings ratio of 54.2. Put this stock on the watch list for now.
