This is saravi's TrustRating, which is based on both the number of reviews saravi 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 saravi has been to the Kudzu community.
I always find something here for my son at Christmas time. Not a large store, but easier to get in and out of than Best Buy etc, but not near the selection. Although I have always gotten great service here!
