Even though Black Friday has historically been known as a brick-and-mortar shopping holiday, consumers are turning more and more to their mobile devices. According to Adobe Analytics, consumers spent $640 million online before 10am today. And what's even more shocking is that sales on mobile surpassed sales on computers for the first time ever. Arthur Zaczkiewicz is an executive editor at WWD, and he joins Cheddar to break down this trend. Zaczkiewicz explains that consumers are spending more time on their phones in general, so this has increased shopping activity. He also claims that retailers have become smarter about their mobile marketing techniques and strategies. Finally, Zaczkiewicz also addresses the concern of over-spending during the holiday season. A study by CareerBuilder found that 78% of American full-time workers live paycheck-to-paycheck. It can be easy to get carried away during the holiday shopping period, so Zaczkiewicz gives tips on how to avoid getting sucked in. He suggests setting a budget before you head out, shopping with a friend, using cash, and most importantly distinguishing between a "want" and a "need."
