If you place an order, you can add more items to your existing order at no extra shipping cost. Up until I mark your order as processed. Just add more items to your cart and then check out. It will ask you to combine it with your other order. If you need something else after I have marked it processed just message me and I can open your order. This is as long I have haven't marked it as shipped. This means I've already purchased and printed out the postage label.Last Updated: 28 Jun 2020
