I've bought a few products recently that have failed soon after purchase. Each time, the manufacturer has arranged to ship me a new one at no cost and minimal inconvenience: Either they sent me a return label (by email) that I could use to send it back to them at their expense, or they sent me a new product, the shipping box for which I used to return the old one to them.
It's interesting to think about how many technological inventions, in how many fields, were needed to make this mode of repair possible.
