Questions about getting fitted

hey guys, since i've graduated college and got a job, my next goal is to get better at golf, i usually shoot around 85-90, been playing for about 5 years but want to really try to get better this year after taking lessons last year i feel good about my swing, i want to get new irons and was wondering if i can get fitted and buy used irons or do i have to buy irons from the store when i get fitted?

i hit my buddies mizuno mp59 and loved how they felt,  however i did not love the price tag and was hoping to get a set of ebay for a little discount

Stores will be different but getting fitted certainly wouldn't force you to buy the product. What you might find is that some places will charge you the fitting fee regardless of whether you buy them or not. So you will be adding $30-60 on top of the price of the product if you buy and if you don't you will have to pay that fee anyway as well.

Other places will charge you that fitting fee if you don't buy but will not charge you if you then buy the product and spend over a certain amount.

Call up your fitter and find out which they do.

Also you might find that some places will let you hit the clubs on a simulator for no charge to see if you like them. The fitters in these places won't be as knowledgeable as pros and you're more than likely going to get a sales pitch to push you in one direction to buy the most expensive option, rather than the one you actually need. If you just want to test a few club though its not a bad option, just don't use it as a real fitting.
