I think if a player rents a new club and buys it within the same 24hr period, that the rental fee should be deducted from the club price.
With all the reviews on the boards and players willing to help either out and give club recommendations, I don't think there's any reason to rent clubs.
The only time I ever rented clubs was during the free rental periods. And the main reason I did that was to get the discount when I then purchased the club.
I would save your credits and just ask others. But that's just me.
