Amazon sells over 175M items during Prime Day 2019, more than Black Friday & Cyber Monday combined

Amid worker protests and antitrust investigations, Amazon's Prime Day sales event carried on as usual -- and that means it again set new records for the online retailer. This time, Amazon says Prime Day 2019 was bigger than both Black Friday and Cyber Monday combined, as Prime members purchased more than 175 million items during the event. While Prime Day 2018 became the biggest sales day in Amazon history, it's getting harder to directly compare one Prime Day sale with another, because Amazon keeps stretching them out.
