If USPS had such great customer service, how come absolutely nobody uses them in the one area they don't have a legal monopoly on (package delivery), even though they're usually cheaper?
A
lot of people use USPS for package delivery, including myself (on the rare cases I deliver packages at all). Excluding one-day (rush) deliveries, they do more business than FedEx in fact.
And, of course, FedEx and UPS both rely on the USPS to handle last-mile duties for several classes of deliveries (SmartPost and SurePost). Obviously
they trust the Postal Service to get the job done.
