Costco Sues Titleist in Battle Over Golf Balls - WSJ. Let us begin with the fact that I buy my golf balls at the Flea Market. When you have no clue where your ball is going, and when 2 out of 3 get lost in the woods, or take a plunge into water, you tend to be careful about how much you spend on them. But, the truth is that buying golf balls is not rocket science. You are not going to improve your score by buying a name brand ball; unless you are a professional who actually knows where the ball is going. Even then, with the right club choice, most professionals actually limit the distance their balls go, for strategic and tactical reasons. So, that said, go to Costco and buy the cheap balls. Nobody except Acushnet and the snobs at the club will care or know the difference. Jeez.
