BackerKit has resolved the problem - it looks like the shipping fee wasn't being properly flagged on IGG's side, thus their importer got it wrong.
If you used your mistaken Bonus Credit, it won't be viable any more, and you'll either need to pass on your credit card info or cancel the add-on to clear things up.
Sorry for the confusion! If you have any more questions about this, please contact BackerKit support and they can help you out!
