I was in Sam Ash the other day, looking at a Nuno N4 guitar.
The sales dude was having some trouble with the terminal and walked away to get some help and left the thing unlocked. I happen to be in IT and decided to have a look around. What I found was on average a mark up of 45%. Totally floored at what these could be going for out the door.
Make sure on everything you’re at least getting 10%
