Last November, I found myself at Walmart, covering its Thanksgiving sale for a California newspaper. But once I finished my reporting, I didn’t even consider following the customers I’d interviewed inside to score a deal on a TV or a tablet. Instead, I joined the hordes of shoppers who take advantage of discounts on Cyber Monday, the online supersale that brought in nearly $2.04 billion in 2014. With the click of a mouse, I bought a pair of Oxfords from the Levi’s website, along with some Pamela Love earrings. The purchases arrived at my front door in a matter of days.
