In the recent quarter Costco recorded a 9.35% revenue increase to $35.5 billion, a 6% rise in comparable same store sales (excluding gasoline prices and foreign currency changes), and 3% growth in net income to $697 million over previous year. Costco also opts for a limited number of brands, which allows it greater supply chain efficiencies as opposed to Wal-Mart or Target. Washington-based warehouse club Costco Wholesale Corporation is outperforming the U.S. retail industry as a whole, which grew 4.2% in 2013, according to eMarketer .
