I didn't write the software - it obviously has some issues - I was presented with the option to pay without divulging the fee for this option, so I clicked on it. I'm also confused as to why the option was presented in the first place. I'm a CPA so yes I'm sure of what I'm looking at and that I was charged $40. I'm looking at a shopping cart/invoice with the 2 charges on it $90 and $40 - that cannot be edited or emptied.
