One of the great benefits of shopping on Amazon is the wealth of customer reviews of both items and sellers. Reading positive customer feedback about an item or a seller can give the customer the extra nudge they need to purchase an item.
Amazon Associates Web Service and Amazon encourage a customer community. Customer reviews are one aspect of the community. Other aspects include WishList, WeddlingRegistry, BabyRegistry, in which customers supply the items they'd like to receive as presents.
All of these features, in Amazon Associates Web Service, are read-only, that is, it is possible to retrieve customer reviews and various customer lists using Amazon Associates Web Service operations but not possible to create new customer reviews or lists. Customers create reviews and lists using the Amazon web site and their customer account.
