Recently I've realised I'm spending a few bob on in-game purchases for a mobile game. While the obvious answer is to stop doing it entirely, I am curious if anyone has any methods to earn/purchase play store or apple app store credit cheaper.

My planned method was to sign up for NX rewards and then earn 20% off by buying a one4all gift card. But with how the one4all card has reduced to 6% on NX and how it seems to be being phased out entirely on it and CS, I am looking out for any alternative methods.
