There is a quirk with the dwolla in that it calculates your total before discounts are taken into account. You will only be charged what you see on the last screen but it authorizes based on the total it has before discounts. Its a quirk but the only work around to it is to just make sure you have enough in there to cover the amount before the discount is applied. You will then be actually only charged what you see on the last screen.
I am looking at a couple of solutions to this so we'll get that fixed!
