Chanel is expensive but the fact that you can send faulty/broken products to them and they will fix them for no charge kind of justifies it, that's at least the case with accessories. I worked part-time at a boutique which sells Chanel and customers would even bring bags they bought 10 years ago and we would send them to Chanel and they would fix them. I mean you'll pay something like €1500 for a bag that you will have forever, it's expensive but you get more for your money's worth than when you buy some tacky, poor quality Dior bag...
