Hey so I have a great bike for sale, It doesn't have much miles and is in great condition. Any more you'd like to know?
Yes. About the chain tensionser. Is that going to need a new part or just an adjustment?
It's not a big deal, you just need to adjust it to an angle that's not recommended by the manufacturer. 
That's good. Would you take $250 for it?
I don't know about that, can you do $275?
If you can do $270, I can pick it up right now.
