Negotiating for Rhinoplasty Price Possible?

Good question and I really respect your tone and your attitude. Some patients come in "demanding" discounts or feel entitled to discounts but your attitude is very admirable and honest. :)
The fact is that unlike shopping for products, services vary in quality. For example, Obagi skin care is the same no matter where you get it from so getting the lowest price makes sense. 
Take it a step further: Whether you are planning on buying a Honda Civic or a BMW 750i, you can "shop around" and find the exact same car with the same features at several dealerships and you can then base your decision purely on price if you want to.  (I would argue that the way the dealership treats you should also be a part of the decision making). 
However, with a Rhinoplasty or any other "skilled service" whether it be a painter or a carpenter, you cannot always compare apples to apples. Each surgeon (or painter or carpenter) is different with different skill sets, etc.
No two Rhinoplasties are the same and Rhinoplasty is THE most complex of all cosmetic surgeries. Revision Rhinoplasty is also much more costly than a primary so you hope to get it done well the first time. Also find a surgeon who will take care of  minor revisions or "touch-ups" which may be needed, down the line, due to unpredictable healing. While bargain shopping for elective surgery on your face is not wise, paying very high prices does not always guarantee great outcomes either. You have to do your research and find the best surgeon and then see if his/her prices fit your budget. It also does not hurt to wait and do the surgery when your finances are more in your favor and not place any financial stress or strain on yourself.
But it does not hurt to ask your surgeon your honest question. Good luck.

Rhinoplasty costs can differ by thousands of dollars even in the same city depending on the surgeon's credentials, experience, and judgement of what needs to be done.  Probably not a good idea to negotiate with the surgeon who will work on your face. 

Most facial plastic surgeons that specialize in rhinoplasty do not discount their services. Rhinoplasty is still in the top three procedures being performed nationally in plastic surgical procedures and is very popular. It is extremely important to go to a surgeon who has performed thousands of rhinoplasties since your best shot is to have it done right the first time. Revision rhinoplasty can get quite expensive and difficult if not done properly. Do not cut corners and make sure you have gone to somebody who is very experienced in all the nuances of rhinoplasty.
