Hello!
Hi there! 
I saw you were selling some binoculars, and I am definitely in need of a new pair. I'm unfortunately on a budget, and was wondering if you would be willing to go a bit lower on the price. How does $325 sound to you?
They're very good quality, $325 seems a bit low to me. I spent a lot of money on them when I bought them and they're very gently used. 
They're a good pair from what I've seen. I don't want to break the bank too badly, would $350 seem more reasonable to you?
It depends. What's the soonest that you could pick them up? I do have other people considering.
I could be over later this afternoon at the earliest, I was hoping to take them off of your hands by tomorrow evening, so the sooner the better.
If you'd like to come over today to pick them up, I can give them to you for $355.
