This is a great offer I'll give you for $165!
Tell me more about the subs. 
Well what exactly would you like to know about? I've had this for about a year, and it is still in really nice condition. 
Are there in other perks to it other than what you have listed?
I have a 1000 watt rms amp that I'm looking to get rid of for just 135 extra. 
Ok, I'm not looking for an amp at the moment. 
That's fine you can get the subs for the original price still!
I've looked at various websites for the same sub and I've seen much lower prices. 
There is a little wiggle room I could provide depending on how much you'd like to spend
I would like to do $99 because I found one for $75 online, but it is too far away. I prefer to have the subs sooner rather than later, but I don't mind waiting if I only have to spend $75. I can offer $99 and pick it up myself so you don't have to worry about a shipping price or the gas to bring it to my place. 
I'd really like $110 for this. Just a bit more than what you're offering. 
I can manage that. 
Great so 110 is a deal?
It's a deal.
