We can’t give discount on app store so instead we charge basic price but offer bonus coins. Ex. Stripe Gold=1,000coins for $10 at 50% off = $5 for apple/google we can’t do 50% off easily so we charge $10+apple/google tax then give 2,000 coins as 1,000 bonus coins so 100% bonus. Make sure products align with this. For apple.google we take the stripe price multiple by apple/google tax so 1.15 google, 1.30 apple then round up to their nearest store approved price.
Base prices stripe, calculate apple/google from these:
Silver $2=200c
Gold 5% discount so $9.50=1,000C, apple ~ $9.50*1.3=12.35(then round up to nearest apple approved price) then give 1,050C for apple/google.
Diamond 10% discount so $45=5,000C
Platinum 15% discount so $212.50=25,000C
