Add everything you are wishing to purchase to the cart (not the watch page, it is different), when you click on pay only this seller it should show you the combined shipping costs. If it does not let you click on the request invoice, then the system has combined shipping costs and you can pay from there. 2. You can purchase everything separately (but DO NOT PAY for each), then in the purchases area of your My eBay page you can pay for your order and the system will combine the shipping charges for you, or IF it will let you, you can request an invoice. All of this works best if you are on ebay.com NOT the app. If you run into any problems or have questions, just ask I am here to help.
