It looks like Amazon's efforts to lure new customers with Prime Day worked.
The online retailer said 2017 Prime Day grew by 60 percent compared to the year before, with more members joining Amazon Prime on July 11 than any single day in the website's history.
And that's the point – Prime Day is essentially a giant advertisement to get people to join the subscription service.
For 30 hours, Amazon dropped prices on thousands of products, ranging from gadgets and TVs to household appliances and clothes. And they sold a bunch of stuff (although didn't provide very many hard numbers).
What did people buy?
Amazon gadgets like the Echo Dot, plus Fire and Kindle devices, were among the most popular items, setting sales records according to a news release. But there were some really random things people picked up, too.
– The thing Americans bought the most of was a programmable pressure cooker – the Instant Pot DUO80 7-in-1 Multi-Use Programmable Pressure Cooker to be exact. (Canadians liked the pressure cooker a lot too.)
– People in the U.S. also bought a lot of the 23andMe DNA Tests for Health + Ancestry kit. Amazon says Americans purchased 200,000 lightbulbs and 200,000 women's dresses using Amazon Prime.
– In Japan, SAVAS Whey Protein and Happy Belly pure bottled water were the hot ticket items.
– People in France and Belgium must be excited for the return of Game of Thrones on Sunday. They bought Game of Thrones – The Complete Season 1 to 6 on Blu-Ray.
Then there's the writeable DVD packs, which Amazon says it delivered in 12 minutes via Prime Now. That was among the fastest Prime Now deliveries for the day, and happened in Sunnyvale and Berkeley, California and Kirkland, Washington. People there also ordered a Samsung Internal SSD and snacks.
