So many things are variable or negotiable, like cars, insurance, car rentals, furniture, mattresses, and houses. I feel like most people get the standard deal but they throw a few people a bone maybe to get good reviews or because the rep likes them.
I think sometimes Karens get a good deal by throwing a fit but you can also just ask, “That’s more that I was wanting to spend, can you do $x?” Doesn’t hurt to ask.
