When a customer bargain with me
I sell something online. One buyer bargain the price with me--offering me a much lower price.
I replied him I can offer offer him a deal which is five dollar cheaper than the original price.
In the end of the email, I writes "Let me know how you think of the deal." I'm sure my expression is surly understandable, but can someone tell me a more professional way to express the same meaning?
Thanx a lot.
