上一封邮件就说免费寄样，但是客户以为快递费都免了，就纠正和他说运费要他出，然后有下单的话就退还给他，结果他反其人之道

The shipping cost are very high and the sample cost are almost nothing. What we can do is you send us the samples free of charge and if
we place a first order than you can charge us the samples and shipping cost on the first order. Thank you

这可咋回啊.....
