Offer arrived, can I still ask for more? - 10 weeks in

I want to negotiate but I am afraid they will withdraw. I am in San Diego, in case local advice matters. The hiring manager was friendly and open. Did you negotiate?

I thanked them and said I was excited but hoped we could talk about the pay. They came back with a bit more.

Ask about the range, not a number on its own. It felt more collaborative.
