Negotiating an offer, is it too late?, forklift operator here

I received an offer as a forklift operator and I think the pay is a little low. It has been weighing on me all week. I have a competing interview next week. What wording worked?

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

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