[求助]不明白客户说的“same"是什么意思！！

我一个国外客户在我们公司询价一款产品，我们也报价给他了。 他说先发两个样品确认，我们的样品是免费给他的，他也同意支付快递费，让我们发一份pi给他，并要求除了快递费，还要在pi里面加入”same"，我彻底懵了，不知道客户说的“same”是什么意思，求给我朋友帮我分析一下啊 ，谢谢了。 客户和我的部分邮件内容如下： 客户： we agree to settle the freight cost along with the order,please add same to the invoice. as this is the policy of our company.we are confident if the price and the quality is acceptable。 我：i am glad to hear that you will pay the freight cost. pls kindly check the invoice below.after payment,pls kindly tell me ,i will send the samples to you as soon as possible. our quality is good,we he many order to eu and the united states each month,with high quality and low price.last month we received a 1 million order from a uk company.right now in production, customer satisfied with our samples. any question pls contact me in your suitable time.keep in touch. 客户： kindly send the samples asap. please add the courier cost to the pi. we shall settle same along with the advance payment. trust you understand same.you need to incur the initial freight cost but add same to the pi. regards
