I wish you good luck, matey!
If you haven't had your guitar set up in a while, and they throw that in free, would that not perhaps help "swallow" the $75 for installation? Maybe you can gripe about the economy or something, make them feel like they need to work for the money nowadays... If nothing else, maybe get some dressed frets out of the deal...
It's just a thought. Kinda like having your gifts wrapped at the mall; you'd have your acoustic ready-to-play as soon as you got home!
