They don’t base company ratings on customer satisfaction, but upon successful delivery of a product. It could be poorly packaged and beaten to hell, but there is no method for the buyer to indicate the seller’s mistreatment of the product. I recently tried to reach out to a seller, who was supposedly local but had shipped a product from the other side of the country, about an issue with the product they sent. I received an automatic response apologizing that my order wasn’t delivered (even though I’d never suggested that to be the case). Don’t even consider buying new books through this site.
