感觉死定了！！！

作为一个销售代表，你的回复还可以改进。建议你在邮件开头先道歉再确认对方是否仍然需要样品，并表明你会尽量解决价格问题。例如：

Dear Sir,

I apologize for my mistake in the earlier email. The price for LJ-MNM001 was wrongly quoted, and the actual price is higher. I hope this does not cause too much inconvenience for you.

I understand that you have requested samples, and I would like to confirm if you still need them. Despite the price error, we are willing to provide you with the samples and you can decide if the product meets your requirements. We will do our best to find a solution regarding the price discrepancy.

Please let me know your thoughts on this matter.

Best regards,
Jenny

如果对方没有回复，你可以再发一封稍微友善一点的邮件催促确认。例如：

Dear Sir,

I hope this email finds you well. I am writing to follow up on my previous email regarding the sample order. We have not received any response from you yet, and I want to make sure that we are able to proceed with the sample order as soon as possible.

If you are still interested in receiving samples from us, please let me know so that we can arrange it accordingly. We understand that the price discrepancy might have caused some confusion, but we are committed to finding a satisfactory solution for both parties.

Thank you for your time and consideration.

Best regards,
Jenny

总之，在邮件中表现出诚恳和负责任的态度，尽量避免使用过于生硬或者批评对方的语言，以免进一步引发误会或不必要的摩擦。
