>Once again, this isn't a pack of oreos you're buying from the supermarket and asking to swap a vanilla in the pack.

That's actually the perfect analogy.

There is no negotiation possible. It's take it or leave it. Toll Brothers don't care if you walk away; they'll turn around and sell it to someone else.

>Swap out the oven or I don't buy the house.

Right, exactly. Except if you insist on this then the result is you don't buy the house 100% of the time. There's no negotiation.
