Hi. I am interested in you bike. Is it still available?
Yes. 
I would be willing to pay for the bike in cash today if you could drop the price just a little. Would you be willing to take $990 for it?
I am pretty firm on the price. It's a rare item. I might go down to 1050 if you can get here today.
If you could drop the bike off with me I would be willing to pay 1050 today.
Sorry, pick up only. If you can come today, I'll do 1000 even.
