I sent a message to customer service this morning, when I was in a fit of panic, asking if due to the mention of free postage in the title, whether I was obligated to send it 'free' and I just got a reply. I was shocked at how quickly they replied!!! This is what they said:

Hello Jane,

Thank you for contacting eBay about the transaction that you have with the buyer XXXXXXX. Let me help you with this.

I checked the listing Jane and I can see it that you listed it correctly. Yes it's showing free postage on the title but the postage and payments page is showing that it's not for international buyers. You already opened an Unpaid Item Case against her. Close it on the 5th day from the date that it's opened and three things will happen.

1. You'll get a credit for the final value fee.

2. You'll be safe from getting negative feedback. Once an unpaid item case is recorded on the buyer's account, she'll be block from leaving feedback because the system will detect that there's no payment.

3. And lastly, an unpaid item strike will be recorded on her account which may result to restriction or even suspension if it progress.

So in this situation, I will not recommend that you send the item to her for free. If she wants the item then send her an invoice with the correct postage cost. 

I'm sorry this sale hasn't run smoothly and I hope I've explained everything clearly. If you need any more help, please let us know.

Thank you for chosoing eBay!

Cheers,

Angel L.

So, I will resend an invoice (assuming I still can with a case opened, I haven't checked) with the postage cost, explaing the best I can and if she doesn't want to pay, then I'll close the case in 3 days time and be done with it.

In the mean time, I will keep revising my listings........although some of them will have to wait to relist before I can revise.
