I like to break down the price on usage. Let's say I spend 1000 euros in a good quality bed made to my liking and is expected for it to last ~10 years, so price is ~0.27€/day. Can I afford that to sleep comfortable and get a good rest every day? Yes.

On the other hand, let's say I spend 600 euros in a waterproof jacket but I live in a place where it only rains heavy enough to use it twice per year. Even if it lasts me 10 years, why pay 25 euros per usage?
