I have chosen to self-host ebooks through Payhip: a division of PayPal. I offer two formats: Mobi for kindle devices and epub for all other devices. I have discounted the price because I receive all royalties from this site, minus the small fees the service charges. If you do not have a PayPal account you should be able to pay with a credit card, I am not sure on this matter, but I can sell print books with the credit card option.
All books currently available will have an MJCPress buy link or you can check the MJCPress link below for all books.
