Good question.
For international shipping, we will invoice after the fact if there's a discrepancy worth worrying about. To that end, if the shipping aggregates to an amount that is too much, we'll refund accordingly... Pretty tough to get the shipping perfected with aggregated orders that can vary in weight so much
Remember, just like last year, we will process the discounts via refund next week...
I'm not sure how available I will be tomorrow (later today). Everyone else at the shop is off and I've got my own black friday plans

... So if you have a question, I'll try, but hopefully you can sort it out on your own. Orders gotta be in by midnight. Based on the first 2 hours of this, I'm not leaving the sale up any longer than that!
Happy hunting!
