As a resident of Illinois, I can’t participate in the Amazon Affiliates program due to a law passed in the state awhile back that was supposed to protect brick-and-mortar businesses from online businesses that didn’t charge Illinois tax. I thought maybe that might have changed since there had been some stories about the law being ruled unconstitutional, but not according to this newly updated boilerplate from the Amazon Affiliates page. I still get their emails, I just have to keep hoping this will change someday.
