Amazon.com, Inc. (AMZN) has terminated its affiliate program in Rhode Island and North Carolina--cutting out website owners who earn money by featuring Amazon products on their site.

According to The Street, Amazon cut off the two states in recent days. The massive online bookseller had already warned affiliates that they would end the program in both states if new sales tax laws were passed.

Here's more from the article: "Amazon, it's worth noting, decided to keep its affiliate program in New York when it passed a similar bill last year. Currently Amazon only collects sales tax in a handful of states, and some say it's taking advantage of a loophole for online retailers."
