we are studying about e-commerce and how businesses use social newtworking to market their products and so forth. i understand that the new wave is to shop online and that you can find things at great prices. Cheaper than that of product in the stores even. To me e-commerce can be a great way to advertise for your business at the expense of others even. If your a individual that is starting out with a small computer repair business, using Facebook to share your  business page  is a great idea for advertising to gain customers.
