Due to the fact that public companies must continuously earn money, they must from time to time establish offers and discounts in order for people to be attracted to buy their merchandise. Be wary of imposters. It is quite normal for scammers to claim they're in connection with a certain business or charity and entice you straight into setting up a transaction or contribution with their company. Whenever conducting business with a seller you're not knowledgeable about, verify their standing with your state or local consumer protection or Better Business Bureau before doing business with them. Never forget to verify if the dealer is an accredited supplier when buying products from an internet seller. People who are employed to work in the government or in huge businesses such as IBM, Oracle and HP are given discount rates when they buy from certain vendors.
