Not a bad maxim by which to live! For all that, like you, even if I were a lottery winner, I'd still want the enjoyment of negotiating a discount 
With the winning powerball ticket in my pocket -
you negotiate - while
I'll be riding off down the road on my new scooter! Not sure which it'll be - but it will be RED.
My late brother was in the car dealer business for 45 years. He retired as the manager of a mega-mall dealership.
He once found an "X" spray-painted under the hood of a new Civic he'd purchased for his daughter -- something to do with a disagreement over the pricing of its first service. When the smoke cleared - they placed a new Civic in the drive for his son.
The family always ran the planned car purchase, new or used, through my brother. He'd place a call - then report back with stuff like : "it's a good price now -
and they're putting on a set of new Michelins."
