I do combine shipping on all orders shipping to the same address.  If you order all of your items at once, you can click the "Request Combined Shipping" link from the shopping cart, and I will generate an invoice with the updated combined shipping cost for you.  I can generally get the invoice out to you within a few hours, but please allow up to a day for me to respond. 

If you don't or can't request an invoice, I will refund any excess shipping costs back to you once I pack and weigh the order.
