This is Jennyt's TrustRating, which is based on both the number of reviews Jennyt 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 Jennyt has been to the Kudzu community.
My recent experience here was great. I had a lot of questions about 2 gift items I wanted to purchase, and the staff was very helpful and kind. I left feeling I had purchased great gifts for my freinds.
