Payment is due through Paypal within 3 days of the end of the listing. I ship within 3 days of cleared payment, but usually within 24 hours of cleared payment. I estimate shipping based on the weight of the item to parts of the country that are furthest away from me. As I live in Iowa, my shipping rates are estimated based on shipping the item to New York or Los Angeles. Don't hesitate to contact me with any further questions.
