Additional context I don't know the size necessary, only that it is large

[Samasaur1]

I believe it stops working at a one with 10 zeros after it (i.e. 10000000000), but that a one with 9 zeros after it (i.e. 1000000000) works. That's what my testing showed

[Samasaur1]

In addition, the stack trace shows that it's a NumberFormatException, while I am certain that my formatting was correct. Perhaps Integer.ParseInt has a limit?

[Samasaur1]

It turns out that my failed values were out of Integer range. According to this SO post, I should use Long.parseLong() instead. However, I can just put a cap on the maximum amount at a time

[Samasaur1]

I think I'm just going to put a cap on it

[Samasaur1]

Although this brings up a good question: Should there be discounts for buying in bulk?

[Samasaur1]

Amounts in buying and selling still need to be redone

[Samasaur1]

Should be done now
