Right now, I'm playing the game "Dragon Bane" that currently hold the Top diamonds (gold) purchase ranking event.
And I planned to spend like $2000 - 2500 for this event within 5-7 days to secure my top 1st ranking.
But with my experienced I always got iTune purchase error after I try to buy more than $200 (2 transactions, $100 each) and after got this error I have to wait longer than 24 hrs later before the next payment.
So, is it possible to unlock the limited amount per day. Or expand higher amount per day of my account for 1 or 2 weeks?
I would guess that no, that will not be possible. Such limits are set in place to help prevent, among other potential abuses, scammers from spending all your money before you can stop them. If, however, you really wish to spend all your money just on a game rating, you can contact the iTunes Store and ask if they can alter that limit for you:
