In the complaint, the organization makes many claims about the USPS to complement its objection to the grocery delivery test. TPA calls the postal service "a government agency and a congressionally backed monopoly" that has legal rights unavailable to private companies.
"Inserting themselves into this industry space would simply be another way for the USPS to expand their reach without instituting real reform, not to fulfill its mandate of delivering the mail on time to its customers anywhere in the country," reads the complaint signed by TPA President David Williams. "This growth would work to push out already established private providers. This action works to hurt private businesses who cannot afford to bring their price down to a level where they can be competitive. A government agency should not be working to compete with American businesses."
