Not sure if you've heard, but there's been a big shift in Amazon's policies over the weekend. They have now walked back their policy that had always allowed a sample to be offered "in exchange" for an honest unbiased review. In light of the new policy, the samples that will be offered via this community group will not be subject to any requirements or obligations on your part. This group is made up of people who currently or in the past identified themselves as "Amazon Reviewers", but the fact is that you now do not necessarily need to leave a review if you don't want to! Pretty cool for the consumers for sure. If you happen to choose to leave a review though, no problem, go ahead - Amazon has no issue with your choice to review any given product that you happen to obtain in your daily life whatever the means. If you choose not to review samples or products you obtain through any given channel, Amazon also thinks that's okay. So, as it's all up to you now, they now request that you never write a disclaimer saying that you've received a sample in return for an honest review. If you write that in the bottom of your review like before, then you would be breaking the rules and you may get yourself and the seller in trouble for violation of Amazon terms of service. This is an interesting turn of events for sure, but overall, it's pretty simple - they want you to do whatever you want to do and to never indicate that you're giving a review in exchange for a sample.
