There seems to be a lot of confusion as to what the Tread Lightly discount is and is not.
A $100 Tread Lightly membership get you access to Affiliate Pricing.
Affiliate Pricing allows you to buy a vehicle at 1% below invoice plus $75. It is not a discount off a negotiated price.
As I understand it, if the dealer is using the Affiliate pricing program he is not supposed to discount beyond that (not including other incentives). The factory then gives them some sort of reimbursement. If the dealer is giving you a lower price he is not supposed to file for that reimbursement.
That being said some dealers will submit for that reimbursement anyway and pass along some of this discount to you. Maybe the factory never checks or that particular dealer is willing to roll the dice on an audit.
For some reason Tread Lightly gets talked about the most but Access Fund is cheaper. You company may also provide you the benefit at no charge.
Check to see if your employer is part of the Affiliate Pricing Program
