Acura Upcharge at Honda Dealer

Took my Integra in to a Honda dealer for a B7 (oil change and brake fluid replacement) because they told me a cheaper price over the phone than the Acura dealer did. Brought the car in and they quoted me $265 instead of $180 for the brake fluid and $84 instead of $79 for the oil change. I tried explaining that it’s the exact same as a Civic Si, and was told it’s just their Acura upcharge.

I was able to get them to take a few dollars off, but not the whole upcharge. Has anyone else experienced this at a Honda dealership?
