This is kodster's TrustRating, which is based on both the number of reviews kodster has written, and how many other people have voted those reviews as "helpful." It's a way to quickly to determine the value of any single review or reviewer, because it's based on how helpful kodster has been to the Kudzu community.
This is such a great place. Everyone is super friendly. They do excellent work and the prices are super low. Sometimes I ask to get my items back the same or next day and they will do it at no extra charge.
