Did Amazon just bring back free or discounted products in exchange for a review?
"The sole exception to this rule is when a free or discounted copy of a physical product is provided to a customer up front. In this case, if you offer a free or discounted product in exchange for a review, you must clearly state that you welcome both positive and negative feedback. If you receive a free or discounted product in exchange for your review, you must clearly and conspicuously disclose that fact. Reviews from the Amazon Vine program are already labeled, so additional disclosure is not necessary. Read more about promotional content."https://www.amazon.com/gp/aw/help/id=201602680
