So... Long story short. I bought a 2021 Trailboss the other day, and recently we had a new Costco store open up in our area. At the dealers advice I became a Costco Member and they gave me the 1,000 Costco discount. Today, Costco calls me and asks if I saw the invoice, and if I saw the Costco Member price sheet? I assume I saw the invoice, but I definitely did not see the Costco Member Pricing sheet. Based on CostoAuto.com, the trucks are listed about $3,000 below MSRP. However, I also got the GM employee discount (not typical) because of the current promotion. Is it safe to assume the GM Discount is not on top of the Costco Members pricing? and that I did get the better deal. Or should the dealer have used the Costco pricing Minus GM Discount Minus 1,000 Additional Costco Savings? Looking to see what others have received, before I question the dealer. TIA
