Had to shift my post here, so:
As of now,
1500 credits cost 156k Cherry Credits to purchase.
750 credits cost 71.5k Cherry Credits to purchase.
2x 750 credits hence cost 143k Cherry Credits to purchase.
So, if you wanna get 1500 credits, it appears cheaper to buy 2x 750 credits than 1500 credits outright. Why is this so? This makes it pointless to buy the 1500 credits pack. Following the trend, 1500 credits should cost less than 143k Cherry Credits. I doubt this is intentional, probably an error. Just wanted to point this out.
Yup, it is for the asian region. Do you mean not everyone has the option to purchase credits via CC?
