Please take a look at some of the information we have posted on our website at:  http://www.titleist.com/customer-service/faqs/106/Counterfeit%20Products.aspx .  You can also check for authorized retailers at:  http://www.titleist.com/find-a-golf-shop/.  We have no "internet only" pro shops so every legitimate pro shop on the web will have a brick and mortar retail store and you can check that retail address.
