I really wish Amazon expose return rate for each product. That would be better indication of customer satisfaction.

Also I wish there was not such a stigma against returning products. That would be a good way to drive bad players out of business. A few times when I returned something I apologized too much but store employees said that I am doing them a favor by returning it because this is how they determine what to stop selling in their store and prevent shier people from buying junk products.
