Shipping for prints will be paid by the buyers. With our current shipping partners, we currently offer delivery up to 226 countries. Each country has a different rate, and depends also on the weight of the shipment.
Each time a buyer checks out, they will choose the country of delivery, and our system will automatically calculate the weight of the item, and generate a shipping price at checkout.
Assuming you intend to set the price of your item to be US$100, when you choose the paper (assuming it's $15), the final price that will appear on your page will be US$115.
So when a buyer checks out and chooses Australia in his/ her shipping zone, our system will calculate the weight, and if it's below 0.5kg, the shipping cost will be US$29.80.
Thus the final price upon checkout the buyer will have to pay to complete the order is US$115 + US$29.80.
