Many brands of products sold in Sears and Kmart stores are proprietary. They include Craftsman tools, Diehard batteries, Canyon River Blues clothing and Kenmore appliances. In addition to the products it sells, the company also offers many services, including auto and home repair. Sears Holdings is a company built on the legacy of Kmart and Sears stores, owner of many well-known brands, and provider of automotive maintenance and home improvement. The company's main operations are the stores in which it operates under the Kmart and Sears brands. Nearly every state in the country has at least one Sears or Kmart store, and some U.S. territories also have locations. The company operates in the retail market, which is a very lucrative sector, but has lost its ability to generate profits and take the lead as a leader in the US market.
