We do combine postage... just add each item to "CART" and when you have finished shopping select "REQUEST TOTAL FROM SELLER" located on the top right hand corner and I will get back to you ASAP.
***** If this feature is not visible (WHEN USING MOBILE EBAY APP) request desktop site within the browser. ALTERNATIVELY buy each item and send us a request for a refund of the combined shipping amount.
Good luck.
