I find if you walk in ready to buy a saw, They will, in australia anyway give you a better than list price deal. The last saw I bought a couple of months ago was an ms660 they list with a 25 inch bar at $1999, some dealers will have a solid bar some a laminated, now I bought mine with a 36 inch solid bar for $1800. Now this probably sounds expensive to those the other side of the ditch in america but when I looked into it I would have saved about $150 to get the detuned version from the states and upgrade it with the dual port muffler etc.
So yes there is a bit of margin on them here, but I do not know about in america.
