That if you bought a product, it would last. You'd never need to buy another one. If something did happen to it, the store you bought it from would stand behind it. They'd fix it. Or give you another. No questions asked.
Now..once you buy it...it's your problem. Not only should you expect it to break, but you should expect to have to replace it...soon. And sure...the store will stand behind it. If you pay them.
