I have. It was right at the introduction of the redesigned model year so people that wanted to be one of the first to own the car were paying roughly MSRP. Costco got me to GM Supplier pricing and a $700 Costco cash card with zero negotiation needed from my side. Salesperson honored it with no hesitation. I was also able to stack Manufacturer discounts (GM Cashback and GM Private Offer) so when all said and done I paid just a little under invoice.
