The description says they "observe." Call them and ask them if adjustments are included. It seems like they know what they are doing from the website, but make sure that the Starter Fit will actually result in bike adjustments if you need them. Of course, changing out a stem, for example, will be extra, but moving the saddle and adjusting your cleats should be included (as opposed to just "observing" and telling you what needs to be tweaked).
Giving you position pointers is good. Be sure to ask them questions and tell them where you feel discomfort.
