According to Amazon, this week’s Prime Day 2019 topped last year’s Black Friday and Cyber Monday combined. Despite competing discounts offered by eBay, Best Buy and Walmart, Prime members purchased more than 175 million products during the annual sales event. The tally is challenging to compare to previous Prime Day events since the e-commerce giant keeps expanding the duration of the sale (this year it was 48 hours, compared to 36 hours in 2018 and 30 hours in 2017). However, the event set a number of sales records, including new milestones for Amazon devices.

As expected, Amazon offered significant discounts on its own hardware. “The Echo Dot, in particular, hit its lowest-ever price point of $22 and was bundled in with some other Alexa device deals, almost as a giveaway,” notes TechCrunch. Among the other top sellers were the company’s Fire TV Stick with Alexa Voice Remote and Fire TV Stick 4K with Alexa Voice Remote.

It was also the best Prime Day event ever for Amazon products including the Fire 7 tablet, Kindle devices, Fire TV Edition Smart TVs and the Echo Show and Echo Show 5.

“Online shoppers spent more than 10 times as much money on Amazon in the first day than they did on Walmart and eBay combined, according to e-commerce research company Edison Trends,” Bloomberg reports. “Sales in the first 24 hours were up 53 percent compared to the same period of last year’s Prime Day, Edison said.”

Coresight Research estimates that Prime Day sales will total $5.8 billion this year. But perhaps more importantly, Amazon signed up more Prime members during the two days than ever before, including internationally in key markets such as India. This provides the company with an opportunity to establish brand loyalty with more global customers. “Prime members spend more than twice as much on the site each year than non-Prime members, according to Consumer Intelligence Research Partners,” adds Bloomberg.

The Amazon press release explains that, “Prime members worldwide saved more than one billion dollars throughout Prime Day,” and “millions of items shipped in one day or faster using Prime Free One-Day, Prime Free Same-Day, or Prime Now worldwide — making it the fastest Prime Day ever.”

“We want to thank Prime members all around the world,” said Amazon CEO Jeff Bezos. “Members purchased millions of Alexa-enabled devices, received tens of millions of dollars in savings by shopping from Whole Foods Market and bought more than $2 billion of products from independent small and medium-sized businesses.”
