I notice I still have the Amazon book store banner up at the top of my page. Some of my readers have software that blocks that sort of thing so they probably never even noticed in the first place.
In any case, the state of California is going to try to extract state sales tax from online vendors selling stuff in California. They will approach Amazon and say, hey, how much have you sold in CA this year and how about handing over the sales tax. Amazon is balking and one of the things they did is discontinue their program of paying a percentage of sales generated through links to people who live in California. So if you do click on one of the book links I have put up and buy a book from Amazon, I no longer get a percentage. Still, I may keep the book store up there because it's a convenient place to list books that I have found interesting or useful.
But discontinuing the commission program seems like a bad idea. Perhaps Amazon was hoping that people like myself who have made a buck fifty in the past year will write impassioned letters to their legislators. Probably won't happen. It's probably good for Amazon to pay taxes. We buyers will pay more for our stuff, but on the other hand, Amazon will have less of an unfair advantage over local retailers. And California won't have to lay off so many teachers and librarians.
