I'd have to pull out my receipt but I seem to remember that the stainless/nickel (whatever it's called) door was ~$300 extra. The regular black door was included with the cost of the stove.
My dealer didn't give me the black door for free option. I think the black door was like $289, the silver was three something and the gold was $489. I really splurged, but I really like the gold trim and door look
