Top Amazon reviewers get a lot of perks writes Lisa Chow:

• Amazon Vine is an invitation only program for Amazon’s top reviewers.
• Members of the program get a list of products at least once a month. They get to pick any two products and get them for free as long as they review the items within 30 days.
• The very top reviewers are often contacted by manufacturers directly and sent products.
• The items range from headphones that cost a few dollars to $1,000 spin bikes.
• There are some restrictions on the reviewers. They aren’t allowed to sell or give away the stuff to anybody else for one.

Find out who the top Amazon reviewer is, how he feels about the stuff he gets, and why experts think this means that Amazon reviews might be biased over here.
