Keep in mind that the extended warranty price is not set in stone. You can negotiate it just like the rest of the deal.
Last time I bought one they started at $2800. I didn't really want it but I offered $1k and stuck to it. They eventually came down to my price and the finance guy told me they pay $600 for it so anything they make above that is gravy.
So if you want it - low ball them. Hard.
