Negotiating an offer, is it too late? (Austin)

I want to negotiate but I am afraid they will withdraw. I worked as a procurement assistant before this. The benefits are decent. What wording worked?

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.

If they say no, consider asking for something else, such as a review in six months.
