This is Spotseller's TrustRating, which is based on both the number of reviews Spotseller 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 Spotseller has been to the Kudzu community.
All went well for quality and service, but when I presented my coupon they went into up-sell mode immediately though low pressure. I purchased some of the services refused others. Left feeling hustled.
