After studying the Amazon.com associates program operating agreement, it seems to me that $2000 is a lot of books to sell before Amazon will send you a check. So, I am going to pass on all commissions credited to the TipJar Transaction Service amazon reseller account to whoever's web pages the referring links are on. To do this, people who put a link to a book on their web pages will need to register with me that that link is on their pages. Initially I will keep track by hand. I will automate this process when I have a chance.
To see what I've got to work with, here's the letter amazon sent me after the first week.
