On April 25, Amazon said it plans to deliver packages to members of its loyalty club Prime in just one day and expects to spend $800 million toward the shipping goal in the second quarter alone. Walmart’s offer applies to fewer products. As many as 220,000 items, which are the most frequently purchased, ranging from laundry detergent to toys and electronics will qualify for one-day shipping. The orders have to be worth at least $35 to qualify. The Walmart deal will be available to online shoppers in Phoenix and Las Vegas and then expand to Southern California in the coming days, the head of its US ecommerce service, Marc Lore, told Reuters in an interview. The service will be rolled out gradually, with a plan to reach approximately 75 percent of the US population this year, which includes 40 of the top 50 US metro areas, Lore said. One-day shipping marks the latest salvo in a fight between two retailers that have consistently tried to outdo each other in everything from online order delivery to grabbing a bigger share of the online grocery market. Walmart started offering same-day pickup in its stores in 2011 and caught up with Amazon’s two-day free shipping two years ago by offering it without a membership fee. It has made progress in closing the gap with its e-commerce rival by rolling out services such as curbside grocery pickup and same-day grocery delivery — options that have quickly become popular with shoppers. Amazon, on the other hand, has hastened to reproduce the assets of brick-and-mortar rivals such as Walmart and has a mixed record with those projects. It is now racing to open shops with top-selling items ranging from books to cell phones; rolling out same-day curbside grocery pickup and gearing up to accept returns at all US Kohls Corp. department stores. “We have been working on this since I have gotten here ... we have been building out the infrastructure for the last few years to support this,” said Lore, who joined the retailer in 2016 when it acquired his company, Jet.com. The vast majority of the order volume for such a service comes from the “first couple of hundred thousand” products, he said. The move will cost Walmart less as orders will be delivered from warehouses closer to the customer and arrive in a single box instead of multiple packages, Lore said. “It is counter-intuitive... but the way we have structured our network, we will see improved profitability as a result of lower shipping cost,” he said. Walmart sends out boxes from multiple warehouses around the country under its two-day shipping program, but with one-day shipping, it is stocking inventory in the closest single wa warehouse to the shopper, Lore said.
