so no tax money goes to post office, is it funded from stamps and delivery fees?
edit:
Overview The U.S. Postal Service (USPS) generates nearly all of its funding—about $78.5 billion annually according to the USPS’s most recent financial report—by charging users of the mail for the costs of the services it provides. Congress, however, does provide an annual appropriation—about $50 million in FY2023—to compensate the USPS for revenue it forgoes in providing free mailing privileges to the blind and overseas voters.
Yes, tax dollars are apparently expended to pay for "free mailing privileges to the blind and [to] overseas voters." That's not "funding the USPS," dingus.
