Online retailer Amazon has expanded its food offering on its US website Amazon.com.

The retailer, which already sells gourmet foods through the site, has expanded the range to include nearly 2,000 basic packaged goods including Kellogg's cereals and Campbell's soups.

The products are available from its health and personal care section. An Amazon spokeswoman added: “We look on this as a drug store, and you are going to find food items in a drug store."
