Not sure where you are getting fit, but the stock price for any TSi driver is $549. This is with one of the stock offerings. If you are fitted into something like a ventus black then it shows as $894 on the Titleist.com site. If you look on the driver site you can see all the available shaft options through Titleist.

Hope this helps and enjoy the fitting.

Wow, sounds like Club Champion pricing or something lol. The partnership with Graphite Design on the TSi series is a great thing to take advantage of if you fit into one of GD's shafts. If I recall correctly, the upcharge on those shafts is $200 which is of course is still a significant upcharge but it's also $100 less than Ventus and other top shelf options, of which the GD options would normally be at the same price point of. I'm a AD-DI guy to the core and play the 6s in my driver, the 7s in my fairway, and the 85s HYB in the hybrid.

I won't attempt to speculate on where that $1100 number came from. Considering different shaft options will lead to different prices and being that you haven't actually been fit yet, how could they possibly know the total price?
