亚马逊买家想让我降价，我该答应他吗？

当然是不要接受他的提议咯！你可以这样跟他说：我明白你是想让我们进行price match，但是很抱歉，我们不能这样做。对于给你带来的不便，我们深表歉意。我给你个模板：
Dear Customer:
We understand you want us to price match this product. Unfortunately at this time we do not offer price matching. I sincerely apologize for the inconvenience this had caused you and hopefully you can and will find someone who will. Again please accept our sincere apologies...
这样就可以啦
