give a brief description on internet book shops and grocery
Online shopping Online stores typically enable shoppers to use "search" features to find specific models, brands or items. Online customers must have access to the Internet and a valid method of payment in order to complete a transaction, such as a credit card, an Interac-enabled debit card, or a service such as PayPal. For physical products (e.g., paperback books or clothes), the e-tailer ships the products to the customer; for digital products, such as digital audio files of songs or software, the e-tailer typically sends the file to the customer over the Internet. The largest of these online retailing corporations are Alibaba, Amazon.com, and eBay.[1]
List of Walmart brands Products offered through the Great Value brand are often claimed to be as good as national brand offerings, but are typically sold at a lower price because of lower marketing and advertising expense. As a house or store brand, the Great Value line does not consist of goods produced by Walmart, but is a labeling system for items manufactured and packaged by a number of agricultural and food corporations, such as ConAgra,[citation needed] and Sara Lee[citation needed] which, in addition to releasing products under its own brands and exclusively for Walmart, also manufactures and brands foods for a variety of other chain stores. Often, this labeling system, to the dismay of consumers, does not list location of manufacture of the product. Wal-Mart contends that all Great Value products are produced in the United States.[citation needed] Otherwise, the country of origin would be listed.
