I love to combine purchases. Put all items in your cart and when you go to check out "request an invoice from seller". I'll box everything and send you an invoice with the combined shipping total. Please do not buy everything separately and expect me to refund excess shipping. I'll do it, but I don't like it. I wind-up paying extra fees.
