I wouldn't assume that. Shops in my area would want to charge you MSRP for upgrade parts, give you a reduced rate on installation labor, and return any stock parts to you... If the bike you're buying is expensive ($2500+) and the upgrade parts are costly (ex: Shimano Ultegra or Dura-Ace) they'd probably waive the installation fee.
