Amazon ceased shipping orders with FedEx Express and FedEx Ground after FedEx declined to renew the retailer’s contract earlier this summer. At the time, FedEx was carrying roughly 1.6% of Amazon’s total package volume, representing 1.3% of the carrier’s overall revenue. Executives said the cost-intensive nature of the retailer’s shipments meant dropping them could open up resources for FedEx to expand its customer base in the broader e-commerce market.
