Member's of Amazon Associates can share products with their Twitter followers by clicking on a Twitter icon, which sends a message and shortened URL to followers.
The messages, which vary the text before the link with terms like "great deal", "check out" and "just saw on Amazon", can be edited by the member prior to posting.
Any clicks on the link that result in a sale will earn the associate referral money.
Twitter users are not required to disclose any relationships they have with brands, so followers may be unaware the member will earn money if the link is clicked on. Amazon Affiliates can make money from referrals from Facebook, but MySpace has outlawed the practice.
