I combine shipping by weight instead of piece to save you money! My store is automatically set up to combine shipping. However, it sometimes overcharges if you get more than about five items. It is important that you make only ONE PAYMENT to receive the combined shipping. If your account is not linked to PayPal you can request an invoice after you commit to buy the items and I can adjust the shipping before payment. I try to refund overcharges on shipping if it charges more than $2 than it should.
