Somehow the order is using UPS International as the shipping method, which I did not select. Looking at my account, I see that this was somehow placed as my default method. I do NOT wish this method used to ship, rather use the cheapest mailing method.
I've fixed the amount in the store credit section, so it should now be showing as $28.87 on the order. Take a look and make sure everything seems good on your end, and just let me know if there's anything else we can do to help out.
