Digital IN, The Digital IN, or The Digital Influence Network was founded by J. G. Sandom as a service to authors. Digital IN helps authors publicize books by selling them Amazon reviews for $12 each or at the discounted price of $11 in quantity. Originally the cost was $10 per review. The Digital IN guarantees anonymity to authors and reviewers. Only ten reviews are posted each week to avoid detection by Amazon, according to The Digital IN's website.
