I have called someone to let them know about price for seo. I told them $x I predict that in a couple of days, he will come up with an offer of x/2. In reality, I would be happy with x/2 but based on experience, I know this person will negotiate the fuck out of me. So I just doubled what I am willing to take. Now the question is, how do I accept his offer of x/2? If I yes immediately ("sure, no problem") it looks ridiculous that I came down so much. how should I accept his offer so my value doesn't go down and I dont end up looking like an idiot? I am thinking: [long silence] "OK, fine" or "normally I wouldn't do this, but I will do it this time" is that good?
