Amazon U.S. Prime sign-ups slow despite expanded promotion, Reuters says

Amazon doubled its Prime Day discount sales to four days this year and touted blowout numbers days after the event. But by one critical metric, it missed the mark, as sign-ups in the U.S. failed to meet last year’s total and even the company’s own target, according to internal company data reviewed by Reuters, Greg Bensinger reports. The world’s largest online retailer registered 5.4M U.S. sign-ups over the 21-day run-up to Prime Day and its four-day sales event from July 8 to July 11. That was around 116,000 fewer than for the same period a year earlier and 106,000 below the company’s own goal, a roughly 2% decline in both metrics, the author writes.
