The more balls you buy at one time, the more they will take from you, not matter how you swing. It happens on all the courses, regardless of where the hazards are or aren't. They are in the game to make money by hook or crook. The balls disappear quicker the more you buy at once. The only way to avoid the loss is to use the freebies. If you buy, you cry.
