I don't think it's what they charge, it's whatever it costs you to return it. Cheapest ground/freight shipping possible. You could probably look it up with the shipping weight going to Lexington, KY.
Usually with Amazon returns, from what ive dealt with, they just deduct an estimated return amount from your refund.
So if anyone who has an order for a tv 40"+ from Amazon, would you kindly start a return process to see? Obviously don't go through with it though.
Heres an example.
