Or even if it's an easily replaceable part, a lot of people are willing to throw out what they have and buy a new one because they think it's easier. Like my mom said her microwave was broken because it would spark up when she ran it, what the problem was that waxed piece of cardboard over the magnatron was soaked through with grease and was causing an arc, so I went out to an appliance repair store and bought a new sheet of the stuff and fixed it for like $3. I have plenty left over should it ever happen again.
