I've taken my car to Precision for a while because it is convenient and they have good coupon offers. But the last time I took my car in for some maintenance they told me that the battery was about ti die and needed to be replaced. I figured since the car was already there and they could probably use the business (this was in the depths of the recession) to go ahead. When I came to pick up the car that evening I found they had charged me $150 for a new battery! I felt ripped off, and now I wonder if I was getting similarly overcharged for all of the other work I had done there.‎
