Buyer: what's the frame size?
Seller: I have an 8 month old trek bike that is 21" multiple speed great gear set. I used it a lot for school and it got me aound until I got my new car. You like it.
Buyer: do you still have the receipt? just want to make sure it's not stolen
Seller: I got the receipt and the little package with all the warranty info as well and it is not filled out so you can still get the warranty on it.
Buyer: it looks great, 600 is a little more than i have, would you accept 500 if i pick it up today?
Seller: I like 500 dollars but I need at least 600 I was going to even ask if you can put in a little bit more like make me an offer at $700. It is a brand new bike literally like a 1 year old baby, I took care of this bike and it is good to go.
Buyer: ah sorry, the most i could come up with is 552, so unless that works, good luck on the sale
Seller: What if you can do payments we can set an arrangement and I will collect 625 in total.
