Introduction: Why Sales Channels Are Shifting Quickly These days, selling stuff works way differently than it used to. Instead of just brick-and-mortar shops or door-to-door reps, companies now show up in more places. Folks might spot a brand on Instagram, check reviews on Amazon, visit the site later, then buy in person. Websites, apps, online hubs, and real-world locations they're all part of how people decide what to get. One step ahead often means seeing what others miss.
