Making up situational dialogue ~ How much did it cost?

The topic of today’s dialogue practice was talking about bike price. Based on the course dialogue, I tried to lengthen the situational dialogue and imagine how I would express it under such situation.

A: Your new bike looks awesome. How much did it cost?
B: It’s one thousand two hundred and eighty.
A: Really? That’s a very good price, this brand is very famous.
B: They said I was the thousandth customer that day and gave me a discount.
A: Wow, you’re lucky!
B: Yeah ! I am really excited !
I never thought I could be so lucky in my wildest dreams.
A: Let’s go to travel by bike together on weekends !
B: Good idea ! Deal ! See you then.
