I'm not sure if the term "classic" can apply anymore. Aside from some upper level executive at Amazon, I don't think there's anyone who is aware and concerned of the scale of the returns they get (most likely due to the products being one of the cases I mentioned). Amazon reportedly has warehouses full of returns that they find cost effective ways to dispose of. It's not like they go back to the manufacturer. In the classic times, the goods would go back to the vendor. And the vendor would have to deal with them -- something that costs time and storage space (and maybe disposal cost). But now the sellers are insulated from it all. To them it is just a loss of profit. As long as the bottom line is positive, it's worth it to them to scale it up as much as is still profitable.
