Just replaced our car battery on Thursday at Advance. Free checkup of the old one that was from Advance 6 years ago. No charge for the changeout either. My son is a mechanic and recommended we stay with the Advance. The first 2 years have full replacement then pro-rated afterward. We used to use Interstate then our mechanic moved and I decided to try a Wal-Mart. Turned out that the one I picked off the shelf had been a return - one of the cells was dry. As we were checking it over at the customer service desk we noticed that someone had written in faint magic marker words to that effect.

That wasn't the first time I've purchased something at Wally World that was a return and had something broken or missing. Kind of ticks me off but they do have good buys if you're careful and check things over.
