Is it right to try to negotiate pay?
I would go as far as saying it is WRONG to not negotiate pay

Of course I am speaking from experience in a different field, but as a dental hygienist I am EXPECTED to negotiate my salary. And I negotiate HARD up front because I know most dentists are very stingy when it comes to giving yearly raises. I have successfully negotiated an additional $7 per hour from what one dentist was offering me; but usually I can get their initial offer up by about $2-3.
I wouldn't recommend talking too much about your commute; I mean, why should the employer care where you drive from? -especially if there are other qualified applicants who live nearby; so the commute shouldn't be your selling point. But, you SHOULD try and sell yourself on why you are an asset and why you would love to take the job and what wage you feel you deserve. Be careful in making ultimatums though (unless of course it is true)....If a wage of less than say $30 an hour will cause you to decline the position then a nicely stated ultimatum might be OK towards the END of the negotiating process (don't just come right out and state an ultimatum up front or they may not want to negotiate at all).
In my experience the key to successful negotiating is ENGAGING them to even start negotiating with you at all. Once the bargaining process has begun, then generally both parties feel invested in the experience and naturally WANT to come to some sort of an agreement, give a little and take a little, ya know?
I've been in some experiences when the dentist just REALLY couldn't stand the idea of paying me over a certain dollar amount, but he could entertain the idea of granting extra vacation time or extra sick time, or paying for my scrubs or CE courses or liability insurance....when the wage negotiations are going nowhere, then if we are at least in the ballpark of an acceptible wage, then I start on with the benefits and perks.
I know of too many people who are timid when it comes to wage negotiations, they feel like if they negotiate too hard they might not get the job. I look at it this way: If I cannot get my employer to even BUDGE a little on issues that are important to me, (like wage) then would I really be happy working there in the long run? Over the years many issues will come up that we will need to collaborate on and if they are completely inflexible I won't be happy there.
Also as someone else stated women generally earn less than men for similar work, (I think it is 76 cents for each dollar that a man earns) and I strongly believe that is mostly because women ASK for less and don't negotiate as hard. Hey, it can't hurt to ask, all they can do is say no!
