求助英文讲价的对话！谢谢

A: How much is that?
B:$10000
A:well ,that's too expensive.If it would be cheaper I'll take it.
B:How much do you think is acceptable
A:$10
B:...Go to hell!

你没有具体要求，我就只有这样随便写写。按照这样自己发挥一下吧?

A:How much is this toy ?
B:It's 5 yuan.
A:Oh,the toy is nice ,but the price is a little high.I'll buy it right away if it were cheaper.
B:How about 4 yuan ?
A：OK，I'll take it .

正需要呢，谢谢！
