It is occasionally possible to buy a bundle deal for "real in life dollars" that exceed your level or tier. I got offered a deal for L90 driver and irons well before I was L90. I deemed it a good investment at the time so took it and still have them at L92 and won't change until L97 or L102.
I'm not sure of the frequency of these deals, can only say mine happened to occur about 4-5 levels before I was technically eligible. (L90 TMs). I was also offered a bundle deal for he Ping L81/83 around L75 but didn't act fast enough - these deals only last a day or 2 when they come up, kind of like the Free rentals you get after leveling up.
