If you purchase a variety of items you should wait for us to send you a revised invoice BEFORE making any payments. We will try and send a revised invoice asap, although there will be a delay on the weekend. If you choose to not wait and pay the full price for shipping on multiple items that is up to you, however we will not refund any amount AFTER you make your payment. We are a real brick and mortar company, keeping track of and refunding partial funds is too taxing on our accounting system. Shipping discounts not available on items listed with free shipping.Thank you for your business !!!081618R
