Chummana: When I go to buy new clubs there is a tier listed...for me it says hack+
Just ignore the tier requirements for pretty much everything. The way you buy new clubs is through the leveling system. For example- If your at level 35 and the club you want is at level 47 then you have to wait till you get to level 47. And if the club you want is at level 24 then you would be able to purchase that club. Hope this helps.
