electronic commerce, allow consumers to shop from home. There are three main types of home shopping: mail or telephone ordering from catalogs; telephone ordering in response to advertisements in print and electronic media (such as periodicals, TV and radio); and online shopping. Online shopping has completely redefined the way people make their buying decisions; the Internet provides access to a lot of information about a particular product, which can be looked at, evaluated, and comparison-priced at any given time. Online shopping allows the buyer to save the time and expense, which would have been spent traveling to the store or mall. According to technology and research firm Forrester, mobile purchases or mcommerce will account for 49% of ecommerce, or $252 billion in sales, by 2020
