I now have Ebay set up to add $1 per additional item for shipping. This will somewhat make it easier to combine shipping as a buyer. You won't need a corrected invoice. If you are going to buy quite a few, say like 10, I should be able to refund some of the shipping cost back to you now. But it will depend on size of box and weight too.
