LPN job offer, question re/salary$$$

I was offered a position yesterday with starting wage of XXXX amount of dollars. I told the DON I would think about it over the weekend, and get back to her on Monday. Well today reading the local paper I see this same facility advertising for a nurse and the starting wage is XXXX amount of dollars, a whole $1.00 more hourly than what I was offered. I really want the job, but why would they offer me $1.00 less starting wage than what they were putting in the paper? Would it be tactful for me to bring this up before I tell the DON I want the job? Now I feel they were dishonest.
