First off, nice looking floorplan
! I love the center island in the kitchen.
Second, the second year warranty is only available on some brands and not all. I'm unsure if it's offered on the Flagstaffs. If it is, there will be a 1-page form in your paperwork. Well worth the $150!
Finally, the extended warranty - the price is always negotiable. More times than not, they'll come down quite a bit. Before you sign up for one, read the fine print to see what is excluded
. You'd be surprised at how much is excluded.
The extended warranties are usually a win for the company and a loss for the consumer. It's like gambling- the house wins most of the time
. But, people do "win" (i.e. they have a claim that's covered and the warranty company pays in repairs more than the consumer did). Are you a gambling man?
