Both Fedex and UPS have had agreements with certain “mail order” retailers (LL Bean?) whereby the carrier will transport from the shipper to the local PO which carrys it the “last mile.” These have been experiments in my view. Fedex does not use USPS to mail to anyone aside from these special contracts. They will use contractors to BFE locations in crazy remote areas of the West and AK...... Neither UPS or FEDEX were close to going under. Fedex never came close to asking for a bailout. I’m a 25 year Fedex employee.
You should start reading the business pages. Then that sort of news wouldn’t escape your attention.
