As I understand it, Amazon and others are required to collect purchase summaries and send that to Colorado, so that Colorado can collect (or enforce?) sales tax for online purchases. So, it looks to me like Amazon is objecting to collecting the information and sending it to Colorado. My opinion is their public objection is to the administrative cost of doing this, but their real objection is erosion of their cost advantage, since the collection of information will lead to more tax collection by Colorado, resulting in a real cost increase to customers for Amazon products in Colorado. Affiliates, which apparently have nothing to do with it, are merely a convenient, minuscule and vocal group for Amazon to throw under the bus. As a vocal former Colorado Amazon affiliate, may I just mention that Tattered Cover, http://tatteredcover.com/ http://tatteredcover.com/ , is an excellent, large, Colorado (that ships nationally), independent book seller. They also have an affiliate program: http://tatteredcover.com/affiliate http://tatteredcover.com/affiliate I'm just sayin'.
