I have all my packages delivered via UPS whenever possible. While I have had a few problems with UPS, they have shown to be 100% better than our USPS.
Private enterprise is more accountable than any government agency and UPS has many employees that have been there 10, 20 or more years so they are dedicated. No govt slackers there.
FedEx is also better than our USPS but they do not compare in service to UPS. I wish we could have UPS compete with FEDEX for regular mail delivery because Im sure private companies would be more efficient and lower cost than the USPS- the USPS loses BILLIONS of dollars and UPS makes millions because of better service.
