A really good Prime Day. Well, technically Prime Days since it spanned two days. According to data supplied by the retail giant, 2022 was the company’s biggest Prime Day event to date, with Prime members purchasing over 300 million items worldwide over the two days. And that translated into some $1.7 billion of savings for Prime members. While Prime members worldwide did the most shopping between 9 am, and 10 am PT on Tuesday, July 12, US members did the bulk of their shopping between 8 pm and 9 pm PT on Wednesday, July 13.
