To send money or to pay for a book I’ve written, you could use paypal. The book is still in manuscript form of unfinished text in 4 chapters. To read a copy of the book, send about 15 USD. I can send pdf documents of the 4 chapters. If you send me cash, include an email address to notify me where to email the pdfs and the password for the chapters that get put up on the book page on this site. Book link.
