Hello, beautiful table, I'm interested in buying it.  Can you tell me what you mean by "it has a rough character?"
It just means that it is handmade and so that light still shines through the joints. The table is in amazing condition and is a handmade piece.
It's a little small for what you're asking and there's no warranty on it, would you be willing to take $270 for the table?  
The price is firm, I have a little wiggle room, but I couldn't go that low. It is well priced for being a handmade piece.
Well I understand that, but I'm comparing it to several others that I'm considering and it's significantly more expensive.  How about if I come pick it up, would you let it go for $350?
You picking it up is necessary and I would split the difference with you at $400.
Hmm that's just really out of my budget, what if it breaks within the first week?  I feel very uncomfortable about no warranty with this table.  
If you pay $400 and pick it up today I will give it a 6 month warranty.
Okay, will you put that in writing when I pick it up?
Sure!
