Dear Supat,
Thanks for contacting eBay Customer Service about the shipping cost of the item Remy Martin Louis XIII Baccarat Crystal Bottle, Stopper, Booklet, Box - 271671771237. I'd be happy to assist you with this.
Base on my research to this item that you have two options for you to purhcase the item, you place a bid or to buy it now. I found out that the seller didn't specify the shipping cost in Thailand and the only way to know the shipping cost is to ask the seller seller. This set up is something to do with the seller listing and I suggest you to ask a question about the shipping cost to the seller. Since you didn't commit to buy the item yet you can communicate to the seller by ask a question that you may see in the listing for the seller. This is located at the middle part of the listing page under " question and answer about this item".
The benifit of asking the seller question first would help you and the seller create mutual understanding before you commit to buy or bid to an item so expection will meet for both of you.
At the same time I will let the seller knows that you will contact them and ask question regarding the shipping cost and accomodate you with your question.
I am confident this best practice will help you in your future transaction.
Thank you again for taking the time to communicate with us here at eBay, I know your time is valuable, and I appreciate you taking that time to communicate with me. I hope I was able to clear up the information for you about the shipping cost. I wish you the best of luck with any future transaction you may have with eBay, as well as I hope you have a wonderful day.
Thank you for choosing eBay, we value your business. Have a great day!
