There is a shortage of truckload capacity.........tractor trailers. As one of the major current issues with the U.S. supply chain, truckload transportation is in exceptionally high demand and the current supply is low. The same is true with labor availability for large-scale distribution centers. For various reasons caused by the pandemic, warehouse worker and driver availability has decreased. In addition, trucking companies have had to manage their equipment more tightly to control costs. As a result, everything takes longer to get where it's going........Amazon orders, groceries, lawn mowers........everything. Product availability at the store level will fill and deplete in a less predictable fashion. You will also notice that rarely will all products be in-stock at the same time. The supply chain is currently messed up. Expect it to be worse during the holidays as demand becomes greater. When the election, holidays, and pandemic are over, we'll return to the normal in-stock patterns. Until then, expect it to be imperfect at best.
