Brendon,
I have no idea as to how much profit they would normally make on a MTB but I acknowledge that bike store owners have to make a living like everybody else. I just want to get the best deal I can.
Is it pretty standard practice to offer to swap seats and tires etc for customers ? It seems to me that most people complain about the original seats and tires etc that come with the bikes. One store only offered me a $15.00 credit for the seat that came with one MTB when I asked to swap for a $50.00 Ergo seat. $15.00!! (cdn).
