The shipping calculator amount is my best estimate based on the approx. weight of the package to be shipped. Please do not pay for your item until you recieve an invoice from me. Sometimes an ounce or two makes a significant difference in the shipping amount, and I do not want to overcharge you. Please Delivery confirmation is included in the cost of shipping. If you plan to possibly make multiple purchases, please notify me of your intent immediately after you make your first purchase. Thanks.
