【Explanation】
Meimei: When you bargain with venders, you can say "太贵了，能不能便宜点儿?" to ask a discount. When you have got a discount, but you want to get more, you can say "能不能再便宜点儿？" it means "can you make it lower than that?"
Laowai: 能不能再便宜点儿？If I want know the lowest price, how can I say that Chinese?
Meimei: You can say "最少多少钱？" "最少" means "at least". Sometimes, the venders may say "最少40块。" "the bottom price is 40 yuan."
