We have offered a rock-bottom price to our regular customers.

　　我们给老顾客最低价格。

　　rock-bottom price是一句典型的美式口语，常常用在业务双方报盘和还盘的对峙中。从字面上不难看出这个短语的意思是：“地板价、最低价”。因此，当美国人说"We have offered a rock-bottom price to our regular customers."时，他/她要表达的意思就是:"We give the best price to our regular customers."、"The price has been reduced to the minimum since you're our old clients."。
