Hi! I saw you girls bike. I would like to buy for $25, and I'll pick it up.
Okay I paid $60 for it though, so I'd like to get a bit more than $25. Could you do $40 if I come and drop it off at your place? its in perfect condition, same as when I bought it.
I'd pay $30 cash if you bring it to me.
Okay I can do that I guess. Thanks a lot for being reasonable!
