My advice for future wellgosh the Indonesian market share. Indonesia has customs regulations regarding the purchase of goods from abroad that could only be $ 50, so if the products are purchased past the $ 50 will be taxed. So my advice, if your buyer from Indonesia, are asking you to make the wrong price or below $ 50 on the overall price along with shipping charges to Indonesia on the invoice that will be provided at the time of delivery, so that when opened by customs of buyer you are not in taxable. This method is already in use by the online shop in uk one of them like a pro direct. if you can implement this, I am sure your buyer from Indonesia will be more and more, and become your regular customers.
