That's because returns are not due to faulty products, they are due to people trying to exploit the system. I have bought hundreds of items on Amazon and never had to send back any. I bought thousands, of different types, on other services and I only ever had to send back two and that due to the fact the seller sent a wrong item. I always do at least a very quick research regarding the seller and the item so that probably helps. But the 30% I can understand is due to people who never intend to buy the product or buy a bunch of them to send some back. I can sort of understand it in some of the categories (for example clothes) but I also see a lot of people proclaiming how smart they are because they surf on the wave of products they never pay for.
