Even if you don't live in Missouri, other states may follow this stupid communistic law. my advice build your business wide and deep with several different affiliate marketing programs.
The following is an email that I received from Amazon last night.
I have just lost my $2,000 a month business model. And spent 5 hours of my time to find other programs instead of amazon to link my campaigns too- because of the deadline.
Greetings from the Amazon Associates Program.
We are writing from the Amazon Associates Program to notify you that your Associates account will be closed and your Amazon Services LLC Associates Program Operating Agreement will be terminated effective August 27, 2013. This is a direct result of the unconstitutional Missouri state tax collection legislation passed by the state legislature and signed by Governor Nixon on July 5, 2013, with an effective date of August 28, 2013. As a result, we will no longer pay any advertising fees for customers referred to an Amazon Site after August 27 nor will we accept new applications for the Associates Program from Missouri residents.
Please be assured that all qualifying advertising fees earned prior to August 28, 2013 will be processed and paid in full in accordance with your regular advertising fee schedule. Based on your account closure date of August 27, 2013, any final payments will be paid by October 31, 2013.
While we oppose this unconstitutional state legislation, we strongly support the federal Marketplace Fairness Act now pending before Congress. Congressional legislation is the only way to create a simplified, constitutional framework to resolve interstate sales tax issues and it would allow us to re-open our Associates program to Missouri residents.
We thank you for being part of the Amazon Associates Program, and look forward to re-opening our program when Congress passes the Marketplace Fairness Act.
The Amazon Associates Team
