Earnings are not guaranteed; you’ll get out of this what you put into it. The more traffic you have on your blog and the more you promote this, the more you stand to earn.
I reserve the right to remove you as an affiliate for any reason, including publishing content I feel is not appropriate to be associated with my products, such as personal attacks, obscenity, profanity, nudity, etc.
Also, the FCC requires all affiliate links be disclosed by law. The complete guide to dotcom disclosures can be found here: http://www.ftc.gov/os/2013/03/130312dotcomdisclosures.pdf and all affiliate marketing must comply with this.
