Amazon.com Inc. is opening its logistics operations more to third-party suppliers as it tries to get business moving normally again. The e-commerce behemoth has started allowing unlimited shipments of nonessential goods to warehouses, the WSJ’s Dana Mattioli reports, as part of a broader plan to resume pre-pandemic business operations. That includes pushing back its annual Prime Day shopping promotion until the fall, when the company’s leaders believe distribution networks will have regained their footing. Lifting the warehouse limits suggests Amazon can now process orders more quickly in its warehouses and handle more inventory after its shipping delivery times sank under a flood of orders driven by the coronavirus lockdowns. Retail competitors have stepped in with strong results in the meantime, in some cases claiming advantages in using their brick-and-mortar stores for fulfillment. Amazon’s shipping speeds have improved, but the company hasn’t reinstated one-day shipping for many Prime orders.

Seafood suppliers are struggling to overhaul their supply chains as the coronavirus crisis undercuts their core business. The pandemic is hitting seafood businesses even harder than the meat industry, the WSJ’s Jesse Newman and Julie Wernau report, crippling many of their key markets as fishermen and processors strain to redirect their highly perishable products. U.S. supermarket shoppers are buying more fish and shellfish to prepare at home during quarantine, but experts say 70% of seafood is consumed in restaurants and the sales to consumers aren’t offsetting the lost business. Fishermen across the country have docked vessels and distributors have rerouted what fresh fish they can towards groery stores and into freezers, while sometimes destroying the rest. Meanwhile, prices for many items have plummeted as costs climb for processors trying to prevent the virus from spreading in seafood plants as it has in slaughterhouses.

A long-running split in the retail sector is accelerating under the coronavirus pandemic. Department stores and apparel retailers along with the goods and services companies that supply them are staggering, the WSJ’s Suzanne Kapner reports, while big-box chains such as Walmart Inc., Target Corp., Home Depot Inc. and Lowe’s Cos., are coping with sales surges. The gap between the general-merchandise and hardware retailers and the department stores was growing even before the pandemic and economic crisis highlighted the fragile nature of traditional business models. Macy’s Inc., Victoria’s Secret parent L Brands Inc. and others reported steep sales declines last quarter, leaving them with mountains of excess inventory. Kohl’s Corp. says it will manage its business “very conservatively” for the rest of the year after shedding stocks as its stores closed in March. Off-price retailer TJX Cos. included a $500 million charge for unsold inventory in its first-quarter loss.
