Combined Shipping: On items that are sold with a shipping charge, we do try to combine shipping as much as possible, which saves money for both our customers and ourselves, if each item is paid for on the same date. Unfortunately, we cannot guarantee combined shipping if the orders and payments come in far apart, even on the same day. Orders that are paid for on separate days will probably NOT be combined.
