The retail ‘grocery industry’ has three main players:

• Wal*Mart
  
  
• Supermarkets (such as Kroger and Safeway)
  
  
• Independents (C-Stores, neighborhood grocers, ethnic stores).

Together, their sales make-up roughly 25% of the $2.2 trillion of USA retail sales (approximately $550 billion).
