The Globe and Mail reports in its Wednesday edition that Walmart, Target and Amazon are all-in on the shipping wars, a move retail experts say will help them maintain a competitive edge against low-cost Chinese retailers Shein and Temu. An Associated Press dispatch to The Globe says that for Walmart and Target, their investments are also aimed at narrowing the gap in delivery speed with Amazon, which remains the king of speed. Amazon packages have been arriving at the doors of Prime customers even faster this year under the company's new distribution model, which divides the country into eight regions and predominantly ships items from warehouses in those areas. The idea, according to Amazon, is to get shipments to travel shorter distances with fewer touch points, which helps the company not only speed up deliveries but also cuts down on costs. Previously, the Seattle e-commerce giant used to fulfill orders from warehouses across the country. In July, it said 76 per cent of customer orders were being fulfilled within their region, up from 62 per cent before the change. To catch up, Walmart and Target have been pouring money into warehouse upgrades, new facilities or other efforts that they say will also help trim costs.
