Hey. How's it going today? I have a great item here and I'm looking to get rid of it quickly. Everything is clearly labeled and you have everything you can see in the picture. 
I am interested.  However, I really only want to pay $8 as I am on a tight budget right now.
THat's unacceptable as you and I know the MSRP is much higher for these items. Please make one more offer that's more serious and we can still do business. If not, I wish you a good day!
I could go as high as $12.
Okay. I can do that ONLY if you can pick it up in the next two hours. Is that cool?
No problem!
