how to get carmax to waive transfer fee?

You don’t. Carmax won’t waive anything.

Go buy your car at a real dealership instead of one that pretends you are their best interest.

Carmax is overpriced on 95% of their vehicles and they won’t negotiate anything. No thanks. If I want to pay retail, I can go anywhere.
Carmax Transfer Fee
It costs Carmax money to transfer vehicles between stores. Why shouldn’t you have to pay that?
They wont. That is an expense you are directly costing them.

They aren’t going to send cars all over the country just so one person can take a test drive and say no thanks.
Thankyou all for your replies and opinions.
Yeah it might be right
u cant.
