Amazon merchants are shifting sales tactics in the face of shortages caused by effects of the coronavirus.

Amazon's logistics chief, Dave Clark, has transformed the retail giant's operations.

Amazon.com says FedEx Corp.’s delivery performance is slipping and will no longer let third-party merchants use the company’s ground delivery network for quick Prime shipments through the holidays.

U.S. shoppers spent $9.4 billion online on Cyber Monday — up almost 20% from a year ago and a record — boosting an already robust holiday shopping season.

In a letter sent to federal lawmakers, an online merchant has accused Amazon.com of forcing him and other sellers to use the company’s expensive logistics services, which in turn forces them to raise prices for consumers.

Ever since Amazon.com bought Whole Foods in 2017 for $13.7 billion, shoppers and investors have wondered how the e-commerce giant would integrate the upscale grocer into its sprawling online operation. Now, after two years of tinkering, Amazon is betting big on quick delivery from Whole Foods.

EBay Inc. sued three employees working at e-commerce rival Amazon.com, alleging that they conspired with dozens of other workers to fraudulently take high-value online merchants from eBay.

Internet searches for “Canceling Amazon Prime” were 18 times higher June 15 — the beginning of Amazon.com’s two-day sale — than the previous day, according to search engine monitoring firm Captify, suggesting shoppers did not want to make a long-term commitment to the giant online retailer.

Amazon.com is tapping high-profile actors, athletes and social-media sensations like never before to maintain buzz around its Prime Day summer sale, now in its fifth year and battling increasing competition from rivals.

Two months ago, Amazon halted orders from thousands of suppliers with no explanation. Panic ensued — until the orders quietly resumed weeks later, with Amazon suggesting the pause was part of a campaign to weed out counterfeit products.
