How much room is there after an offer?

I received an offer as an electrician's helper and I think the pay is a little low. I do not usually post, so bear with me. I have a competing interview next week. Did you negotiate?

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

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.
