Amazon’s fourth annual Prime Day, starting July 16 at 3 pm Eastern, will drive an estimated $3.4 billion in global revenue for the e-Commerce giant, but its popularity has forced other retailers to take action if they want a piece of the pie. Retail’s biggest players, including Walmart, Target, eBay, Best Buy and Macy’s have implemented sales of their own to align with the event, with Kohl’s holding the “It’s A Big Deal” promotion on July 10. The decision by these retailers to capitalize on a “Black Friday in July” promotion makes sense when looking at last year’s sales totals. The biggest beneficiaries of these campaigns will be large retailers with more than $1 billion in annual sales and niche retailers with less than $5 million in revenue, according to research from Adobe Digital Insights. In 2017, the $1 billion+ retailers saw a 34.9% sales lift on Prime Day, whereas the niche retailers reeled in 17% more than usual. However, everyone in between $5 million and $1 billion in annual sales actually experienced a sales loss of 0.5%.
