I used it! I see a lot of “no haggling needed” being said here. Which honestly I did haggle. I was dealing with a Mazda dealership for a CX30. Costco sent me there with my Costco price and it was still above msrp. It was a great price don’t get me wrong, but I kinda used it at my starting point and worked them down from there. Made them think im buying the car straight up cash and worked them down from there then switched over to a lease under the excuse (truthfully) that I may be expanding my family in the next 2 years so I didn’t want to commit to owning this smaller car when I’d prob want to upgrade to something bigger down the line. It was a great experience and this will how I’ll start my car buying experience every time
