A question about combined shipping

I recently purchased 3X bin items of the exact same thing. The listing said that the seller combined shipping but only on exact items. That's fine because I purchased 3 off of the same thing from the same listing. I won them about 4 days ago and the buyer has never sent an invoice with the combined shipping price. I have emailed the seller on three occasions and requested a total payment. The seller hasn't responded and still hasn't adjusted the invoice with the combined shipping fee. The shippng on the items comes to $20.79 all together which really he could send for about $7 but I don't know what the combined shipping is so I don't know what to pay. What should I do? It's been 4 days and I don't want to be hit with an unpaid strike.|||Pull the seller's contact info(phone) and call them if not an international sale Link It is always a good idea to ask for a firm quote for combined S&H , prior to bidding. Example email: "If I win auction numbers, can you give me a firm quote for S&H to postal zip (Your zip code)?" I have always found this to work well. When the seller answers with the quote, save it by flagging the seller's responce in your MY Ebay messages.|||Do you know the correct total? Was the discount spelled out in the auction or did it just say combined shipping? If you know the total, logon to PayPal choose Send Money then choose Pay For eBay Items and edit the total and pay there. If you don't know the total, in the future always ask before bidding. Send an email to the seller's direct email address. Should be on the end of auction notification from eBay. eBay's message system does not always work properly.|||Great advice. I guess I sort of overlooked the ask before bidding thing. It doesn't give me an exact quote on price of shipping in the listing. It just said "I will combine shipping for all alike items". I guess I probably should have emailed before hitting the bin on 3 of them.
