Amazon announced that it will launch a four-day Prime Day discount event.

Amazon announced on Tuesday that the company's annual Prime Day promotion will take place from July 8th to July 11th, extending the event from two days to four days compared to last year. "We extended the event to four days because our members told us they need more time to shop for discounted items," said Jamil Ghani, Vice President of Amazon Global Prime. Rob Garf, Senior Vice President of Strategy and Insights at retail marketing company Cordial, said that as Amazon expands Prime Day, American shoppers and retailers are facing uncertainty about how tariffs will affect prices and product supply.
