New York (CNN Business)Costco is once again placing limits on purchases of toilet paper, paper towels and cleaning supplies.
The Delta variant continues to spread across the globe, sending demand for those items higher. But that’s not the only reason why Costco is limiting purchases. The warehouse store is also having trouble finding trucks, drivers and shipping containers to get the items to its stores.”The factors pressuring supply chains and inflation include port delays, container shortages, Covid disruptions, shortages on various components, raw materials and ingredients, labor cost pressures and truck and driver shortages,” said Costco CFO Richard Galanti, speaking to investors after reporting quarterly results Thursday evening. “Various major brands are requesting longer lead times, and in some cases, difficulty in finding drivers and trucks on short notice.”Last year, Costco and other retailers were having trouble keeping those products on their shelves because of panic buying by customers worried that they wouldn’t be able to buy them in the future. Manufacturers were also unable to keep up with the surge in demand.Although the increase in Covid cases may be causing an increase in demand for some items, Galanti’s comments focused more on problems getting the products to the stores. He said the problems with the company’s supply chain is causing it to order items earlier than it might otherwise.Read MoreNike is scrambling to fix supply chain problems as holiday shopping loomsRather than just pay to move containers of freight from Asia to North America, Costco has chartered three container ships, with each ship able to carry 800 to 1,000 containers at a time.
