warrantys are sales tools, they rarely help the purchaser much. wheres
your original invoice?

You keep all of that stuff, and not just in case you ever need to invoke the
warranty - you keep it for tax or insurance purposes.

You keep this stuff in a file folder in a drawer - it takes a few second to
put it there when you buy something new. Or in the case of something like a
water heater, you put it in a plastic bag and tape it to the appliance.
