Answer:
Basic Fees
The entry fee for a PGA Tour Event has been $100 for a long time. It is the player's responsibility to confirm with each tournament committee that they intend to play that event, and have their application completed and in the tournament office before the deadline for that tournament (usually the week before). They do not have to pay for each day of a 4 day tournament, and they do not have to pay for any practicing they do, or practice rounds they play.
