People attend Shoptalk, a retail and technology conference in Las Vegas. If you weren't at Shoptalk in Las Vegas last week, you missed a great conference. Shoptalk has evolved into a must-attend retail event with more than 8,000 attendees and growing, a destination where retailers and brands go to learn and collaborate and where networking opportunities are key. The conference included content on the latest retail trends around technology, data, and wins and losses in the online vs brick-and-mortar battle. Here are my key takeaways from the conference.
