I am doing a science fair project on what type of golf ball goes the farthest. I need 2 piece golf balls, 3 piece golf balls, and 4 piece golf balls a low price. Can anyone tell me the cheapest brands of each ball?

Ask your friend who lives by a golf course.

Answer by GBeck
Goto a golf course and ask them if they have used golf balls on hand. Sometimes they pay people to pull them out of water hazards or they buy them from other people.
