To request an invoice from us that combines shipping please use the Cart feature in eBay to add items until you are done. Then hit the Request total from seller button. If you don't do it this way eBay will force you to make immediate payments for each item you buy and you will be charged excess postage in many cases.  This works for Buy It Now auctions. eBay always sends an Instant Invoice but you should not pay immediately if you intend on combining shipping to save money. You can either request an invoice directly from the eBay shopping basket page, or on the first page after you've clicked Proceed to checkout. You'll see a request total button in the shopping basket if there are at least 2 items from one seller from different colors to different categories.
