But you can easily earn a substantial amount of money from each individual customer, making it well worth the arduous setup required.
Once you sign up to become an affiliate with ClickBank, you will immediately be able to browse the different products available to sell. ClickBank has tens of thousands of products available, so in the beginning it's helpful to search by niche and commission percentage until you locate offers that you want to promote. Make sure you take the time to look at the vendor's sales page before promoting their product. They might be offering a 75% commission rate, but if their website doesn't look trustworthy or put together you aren't going to generate many sales, no matter how much traffic you drive their way.
In April 2008 the State of New York inserted an item in the state budget asserting sales tax jurisdiction over Amazon.com sales to residents of New York, based on the existence of affiliate links from New York–based websites to Amazon. The state asserts that even one such affiliate constitutes Amazon having a business presence in the state, and is sufficient to allow New York to tax all Amazon sales to state residents. Amazon challenged the amendment and lost at the trial level in January 2009. The case is currently making its way through the New York appeals courts.
