禮貌地回復說“該商品不打折”就好了：
“Thank you for your inquiry, but unfortunately no discount is available for this product.
Our prices are set to be low and competitive on Amazon.com. You are more than welcome to order from us at the listed price. Thank you and have a great day!”

把他的郵件標記為“no reply needed”，或者回“Sorry, we don't haggle”（我們不接受講價）

每次碰到這種問題，我都會想“亞馬遜會怎么處理此事？”
一般亞馬遜會發一封官方郵件給買家，但內容經常與買家的問題無關：
“We're sorry you are having trouble adding items to your Shopping Cart.?
Please be advised that your case has been referred to the appropriate Technical Support Team.?
Thank you for shopping on Amazon!
（對于您沒辦法把商品放入購物車一事，我們非常抱歉。您的case已由我們的技術支持團隊受理，請放心。）”

這個客戶的要求還挺無理的。你可以說“All of our items are firmly priced. Thank you for your interest.”
如果他再砍價，你就把價格提高吧lol

對啊，這又不是在ebay。ebay還有“Make an Offer（報價）”的功能，可亞馬遜沒有

謝謝你們哈！我是這樣回的：
“Dear Mr. X:
Thank you for your inquiry.
Unfortunately we are not able to honor your request. We do our best to price our product competitively, taking into consideration the scarcity of the product and our original cost in procuring it.
We do hope that you will be able to find the product elsewhere that will meet your needs.
Yours sincerely,”

買家出的價格要是在可接受的范圍內（看利潤如何），我們就說，在24小時內，我們會按他給的價格出售產品。如果他下單，那皆大歡喜；如果沒有，那也無所謂，時間一過，價格就恢復原樣

這種人就是想碰碰運氣，不用理他。一旦你跟他在那耗著，那就沒完沒了了
要是你覺得實在是不能忽略，那就讓他去ebay逛逛吧

經常有買家提這種要求。有些還挺奇葩的：有人說產品要被用于慈善事業（我讓他出示相關資料，他就消失得無影無蹤了）；還有人說是給殘疾人士買的。以此來博取我的同情，進行道德綁架。然后我一般是這么回的：
“Thank you for your interest in XXX item. We price all of the items in our store to be competitive based on market value. Our item is already the lowest priced option on Amazon, so we aren't able to offer any additional discounts at this time.
Thanks again!”
如果發了郵件沒用，他們還是一直纏著要打折，那我就把郵件標記為“no response needed.”

這種不是客戶 是reviewer 不用管他
