Many posts contain products or services that I was contacted to review. Many posts just contain items I wanted to review. If I was contacted to review the product, I post that on the post. If there is a product link to Amazon, then that is an affiliate link.
Sage and Zoo routinely contains third-party advertising and links to external third-party websites. By providing advertising and links to other sites, Sage and Zoo does not guarantee, approve, or endorse the information or products available at these sites, nor does a link or advertising indicate any association with, or endorsement by, the linked site to the Sage and Zoo website. Sage and Zoo has no control over and makes no warranty or guarantee regarding the quality, usability, safety, morality or legality of any aspect of the items listed, the truth or accuracy of the listings or the ability of sellers to sell items or honor their coupon or promotion.
However, I would not link to a company unless I personally have used their product or service, or had a client that has used their product or service.
