Without buying tickets on PSN store, players can have a fully upgraded custom club too.
You can upgrade the club 10 times, every upgrade cost 10 Gems, thats 100 gems that you will have to farm to get your max level club.
You can have 1-4 gems everytime you play a 9H or a 18H round on special rank.
Or you can find gems on the online open courses, you can have 1 or 2 gems per course everyday, thats 12-24 gems daily, not counting the DLC course.
Or you can have gems by doing the fishing mini game (i haven't done this myself)
Once the club is fully upgraded, you can have the club forever, but it will break after 180 holes ,to repair the club, you will have to spend another 10 gems.
So 1 PSN Store ticket = 10 Gems
To fully upgrade the club you will need 10 tickets. thats $8.49.
Thats a shortcut IMO, to unlock the best club in the game, but people likes to call that P2W.
Also you need to level up your skills for every type of club in the game, You can't pay money to have this done, this is the big grind that we all have to do in the long run.
