The US Postal Service said it jumped into action after a tornado destroyed an Amazon facility in Illinois and killed six workers inside in December.
The night of the tornado, a USPS accounts director reached out to Amazon, and the two organizations hashed out a plan the next day, December 11th, to keep deliveries moving.
Five days later, the first packages were redirected from four Amazon fulfillment centers in Illinois, Missouri and Oklahoma to the USPS package processing center in St. Louis.
