I get info from them a lot and have purchased from them, but have never seen Titleist clubs on their site.  They tend to deal in closeouts and carry some Titleist golf balls and hats.  The are not on the published list of golf shops and fitting centers on the Titleist.com site.   I'm sure the TT experts will have an more definitive answer on this one.    

They have AP1 and AP2 irons on their site. Ordered a set. Called to ask them and she said they were an authorized dealer. Just trying to do some research. Thanks

Rock Bottom is not an authorized Titleist account. 

The clubs shipped and i received them from Acushnet

I've used them for other merchandise.  The clubs are likely legitimate.  My to /3 concerns - 

1.  When not authorized, Titleist no obligation to offer warranty service.

2. Essentially buying off the rack .  Getting fit is the best reason to buy Titleist

3. My club is an advanced fitting center, I get fitted and a better price.  There is also an Oregon shop with.an Internet side business that is also lower priced.

Doesn't sound good.... 

Hi Zach,  They are not an authorized Titleist dealer.  You can check for all authorized dealers by going to http://www.titleist.com/find-a-golf-shop/, and putting in their zipcode.
