Amazon Vine is a program created by Amazon that allows manufacturers and publishers to receive reviews for their products on Amazon. The program is invitation-only and selects the most insightful reviewers in the Amazon store to serve as Vine Voices. Vine Voices have the unique opportunity to order items free of charge and share their product experiences with Amazon customers to help them make informed buying decisions. Companies pay a fee to Amazon and provide products for review. Once enrolled in Vine, Voices may request products from thousands of brands selling in the Amazon store which are shipped to their doorsteps at no cost. They then use the products and provide insightful reviews that reflect their honest and unbiased opinions - positive, neutral, or negative. Reviews of a product ordered through Vine appear in the same location as other reviews. Amazon Vine reviews are distinguished with a special badge "Vine Customer Review of Free Product" for full transparency. The Vine program operates independently on Amazon.com, Amazon.co.uk, Amazon.fr, Amazon.de, Amazon.ca, and Amazon.es. The program has received mixed reception, with some people criticizing the programs use of non-professional reviewers while others cited this as a benefit.
