There are literally hundreds of review clubs and review groups out there. I have done a few over the last two years, with positive results. I don’t do them a lot these days as I have more review offers than time, and I don’t need to seek any others. However, for a new reviewer, this may be just the thing to get you started.
Facebook is home to many of these groups. Each one has different rules and terms. Some give product free, some do random drawings for product give-aways, some require you purchase product at a discounted rate, and some require you to have YouTube and other social media accounts to post reviews to. It will be up to you to find out the particular rules for each group to see if it’s right for you, but I’ll give you a list of the ones I know about, and you can request access to the group(s) of your choice.
