Cyber Monday is expected to continue the trend of clicks over bricks. Americans are choosing to shop online rather than head to stores as the National Retail Federation says an equal number of people went to stores over the Black Friday weekend that shopped on the internet. Companies, like Amazon (AMZN) continue to offer deals as the NRF predicts 121 million Americans will shop today online, down from 127 million last year and retailers spread deals over several days. Meanwhile, Retailmenot.com says nearly 80% of American workers plan to shop online today, while they are at work. Leaders from hundreds of countries are gathering in Paris today to hammer out an international agreement on climate change. Known as COP21, the leaders of the main greenhouse gas producing nations-the United States and China-will meet to address how to reduce their carbon emissions. Regulators are reportedly preparing to block the Office Depot-Staples merger (ODP) (SPLS). The New York Post says regulators are worried about a tie-up that will result in a single nationwide office supply giant to serve big corporate and government clients.
