お返事、ありがとうございます。
とても感謝しています。
しかしながら、あなたがご提示下さった金額はeBayで購入するより高額です。
今後長くお付き合いさせて戴くつもりです。思い切ったお値引きを希望します。
宜しくお願い致します。
Thank you for your response.
I really appreciate it.
However, the price you are offering is higher than that of the eBay.
I would like to continue doing business with you for many years to come. I would appreciate a substantial discount.
I look forward to your response.
