I think you posted in another thread and I mention it there, but if you want to save some credits while playing on mobile coin games, grind your winnings up to where you can rent the coin set rental for 50,000 coins.
It would give you a reasonable set of clubs until you reach the higher levels where some of the better drivers and irons can be obtained. You can swap out the wedges with your newly purchased AVG wedge and possibly other clubs you already have.
Also remember since you are playing mobile, while playing mobile you benefit from the sponsor boosting apparel that can "upgrade" your lower end clubs. These will buy you some time to mindlessly click through videos to save up for the better clubs while doing something else.
You clubs of course will play slightly different if you later enter a ranked round tournament where you no longer get the sponsor upgrades but if you are focusing on just enjoying a few coin games this can help defer or offset the cost for a little while. I did this for a few weeks and other than the AVG wedges around L39, my first club purchases wasn't until L51!
And while L51 sounds like a long ways off it is only around 33,000 XP which is very little compared to trying to level up just one level in the upper 90's which will take upwards of 250,000 XP to move up one level! This is why club purchases at the lower levels don't last as long as they do at the upper levels and higher tiers. Your CC may also use the custom courses to earn extra XP''s as many do.
