Whether you are starting out as a blogger, are a seasoned pro, or are somewhere in the middle, I have a resource for you. ProductsForReview.com is a message board of sorts for product and review offers alike.
Are you looking for items to review? You can put up a request for brands to see. You will need to provide details, to make sure that it is legitimate and that the brand that sees it can tell that you are right for them.
Now, they offer brands the opportunity to post product offers as well, so if you are subscribed to their list, you can see what products are available to review.
What an amazing resource that you must try out. There is a very small fee for listing a review request, but it is well worth it. I have been a member for a few years now, and am very happy with the service!
