STD Check has over 4,500 testing centers in America. They don't allow at-home testing, but they are as discreet and confidential as possible. They have competitive prices in the market; some tests are cheaper than what you would pay in a doctor's office. They accept different forms of payment, including cryptocurrency, credit cards, prepaid cards, PayPal, or even gift cards. You can order the tests online, get tested then pay after the tests are done. There is a ten-test panel that checks for all the major infections, including hepatitis A.
