My battery was giving me trouble for 2 days ( as well, a mechanic friend told me that it was low when doing a scan on my car) so I called JiffyLube/Walmart as I bought my battery at a Walmart and it had a 3 year replacement warranty. I called first and spoke to Derek who was super nice and explained everything to me. I said I'd go there right away. While driving there, I noticed that my interior light was on (my mechanic friend asked me to turn it on for the scan. D'oh!!) and that was the reason why my battery was giving me trouble for the last few days! I went there anyway and Derek tested my battery and told me that it was fine. I offered him a tip for his trouble and he refused it. I felt that he was honest and super nice, I will definitely go back there in the future. (He also helped another lady get quicker service since she had to pick up her child). read more
