If you want to expect to pay one price then find out later you were charged $55 more and they won't do anything about it when it was their associate's mistake head to the Avis rental car area in the sears/meadows mall.
I was told I would have unlimited miles and my reservation was changed but later found i was charged $55 more dollars and nothing could get resolved.
Jessica over at the meadows mall location was so rude to me during 2 phone calls and even told me why waste the time calling. she lied once, blamed the other Avis that i dropped the car off to, and then the 2nd day acted nice as I said I was calling corporate. On day 1 corporate was willing to refund me $20 but when I said that wasn't right and I wanted my full $$$ back and I day 2 corporate person said they couldn't do anything for me.
Lesson to be learned. DON'T Trust peoples' word even after you verify it many times. Read the small print to see how they can screw you.
