Janie, I have the same problem. We used to sell things on Ebay, which makes it easy with a customized shipping calculator. Maybe Etsy will adopt that eventually. In the meantime, I do my best to set shipping at an average based on the size of the pot. A mug might cost 6 dollars to ship near by and 9 to ship to the east coast. So I set it at 8 (round up for packing material). In the end shipping & packaging cuts into the actual selling price, but I'm afraid to set it too high. Maybe we should be putting something in our shipping policies explaining that Etsy doesn't have a shipping calculator so we work with an average cost.
