"Insufficient Funds" error in League Store when trying to make purchase

It’s looking for the amount needed before the reducer was applied. If you get above what it would cost before the reducer, it will allow the transaction and take the correct amount from you.

@EA_Blueberry Now that I have more than it thought I needed I was able to buy that item at the correct amount. 

But the Bug is still there.

Because I can have more coins that it shows for the cost and it still won't let me buy it.  There is definitely an issue with the code on that calculation.  Being and IT person, I understand why it happens.  Either way, there is a bug in that Store code.

@EA_Blueberry 

Can you please pass on that logic wise this make no sense at all.  If I am on Amazon, to buy any item with a $80 gift card.  If that item is $100 original price but is 20% off.  I can buy that item with $80 gift card.  I don't have to have $20 additional dollars to buy the item at $80 dollars.  I simply give them $80 for the item. 

I agree with @lkbroach, it isn't based on the full price either.  There is a discount below the full cost that it will let you buy it.  I am guessing the code checks the first level discount to see if you have the funds to buy.  Then if you have at least that amount it will allow the transaction to go, but only charges you the final discounted Price.
