Can't purchase 750 coins

Need clarification I'm not insane. So I have 54.82$ in my iTunes/AppStore account. When I go to purchase the 750 gold coin package in game it says I have insufficient store credit? (see uploaded picture for reference) it already did this to me yesterday so I bought 2 270 coin bundles instead thinking oh there must be an in game service charge and I only have 50$ in my account. Which then left me with 4.82$ which is why I have 54.82$ in my account now. Can someone please tell me if this is an in game glitch or if there is some ridiculous service charge on buying coins and I am legitimately short money in my account. Thanks.
