@erikalogie one thing to consider is if we want to round up the currency amount when in USD because when we cut the decimals o two we may end up charging less than the actual credits price - let me know what you think

@erikalogie @S4mmyb any thoughts on this?
Imagine the exact amount is $10.897, should we charge 10.89 or 10.90?

I think we should round up to $10.90 in this case

Ok so if it were $10.894, we would charge 10.89.
