Nice thing about Titleist is the fitted clubs are the same price as retail store off-the-rack prices unless you get a shaft that requires an up-charge. Go on-line to any retail site like a Carl's Golfland and you will see prices for current models and any remaining stock of previous models. The previous models can't be ordered to your specs, will be limited to what they have on hand. Suggest you do a Titleist Thursday fitting first so you know what your basic needs will be on lie, shaft flex, etc.

I’m in the UK and as Dale said my fitted clubs which were 1/2” longer and two degrees up in the irons were exactly the same price as a standard set. There are a number of non-cost options for the shafts too so you can still find the right shaft without it costing the earth. It only took 10 days from order to delivery too.
