Mine was a few years ago but the great dealer i use and c8 Trained Tech gave me good prices for fluids. Before you think about using another retailer, who makes a profit on the supplies, ask your dealer IF there is a discount available! Sure the dealer makes a profit selling parts and fluids. BUT he also has a staff of servcie writers, shop, skilled tech that he sent for training etc. The wholesale retailer does not.

IMO bring your own materials and asking the dealer to use his trained tech to install is about like going to a restaurant and asking to bring your own beer!

Just show them my Invoice and ask if they can provide a discount on parts.

Did mine a couple weeks ago. Rock Auto for AC Delco fluid. Bought a OTC fluid transfer pressurized pump from Amazon. Bought 11 bottles and the car took around 9 to refill.
