Tesla dropped the price twice in 3 months though. And it's a huge price purchase. I think there's justification. It's not like you're buying a dish washer.
Besides that, a Tesla is a luxury item, these buyers are owed nothing and are acting spoiled and entitled.
It's common for US companies to reimburse the difference in price after a short while, usually around 30 days. Costco and Amazon will do this.
I would be pissed off if I'm a Tesla customer.
