I’ve paid $760 for the same thing back in 2015 and didn’t feel ripped off then, but a quick search on RockAuto is showing a bunch of different options for $75-$150 range. Times have changed.

If the place you went is using all OEM(original factory spec) sure - $760. If your goal is to get it done cheaper and aren’t someone who’s needlessly obsessed with keeping everything OEM, it might be worth calling a couple different shops. It shouldn’t take a VW specific mechanic for a brake job.
