Before you make a purchase on a website or head to a restaurant, click on the company's Twitter and Facebook pages to check for discounts. You don't have to be a registered user of Twitter or Facebook to see these discounts!
Twitter profiles for companies and their Facebook pages are public, so anyone can view them. If you can't locate the Twitter and Facebook buttons on a website, which are usually very easy to find, simply Google the name of the company and Twitter or Facebook.
Of course, if you regularly follow a company's updates through Twitter or Facebook, you can ensure you don't miss any discount codes and promotions. These two clicks can potentially result in substantial savings!
