A Purple Star is a common thing that eBay customers will notice when they purchase from certain sellers on the platform. This star rating denotes that the seller has had a fairly substantial amount of ratings given from past customers who have bought from them.
An eBay seller's Seller Rating is one of the most important pieces of information that a customer can use to gauge their reliability and responsiveness to consumer needs. These seller ratings allow customers to know what previous buyers have said about purchasing from the eBay seller in question.
Seller ratings on eBay take the form of color-coded stars. These stars are based upon the total number of ratings that a seller has received. Sellers on eBay with a Purple Star rating have received anywhere from 500 to 999 ratings from past customers who have bought from them. This makes a Purple Star an excellent metric that a customer can use to gauge the quality of the specific eBay seller.
Customers can get a good idea about an individual seller by combining their star rating with their overall positive feedback score/percentage. This means that sellers with a Purple Star will have a significant amount of feedback available that a customer can take a look at.
