I do offer combined shipping discount. To get a combined shipping discount, all auctions won within a 3-day period must be paid for at the same time. Please let me know that you plan on bidding on an additional auction. Also, disregard eBay's request to pay now for your first auction win. I will send a combined auction invoice which will have a shipping discount.
If you are unhappy with your purchase, please contact me before leaving feedback. I will work with you to resolve the purchased issue. I will leave you feedback after receiving your feedback.
If you have any questions, please ask. Thanks for looking.
