This weekend my autozone battery went belly up. Today I finally got to the store and they verified it was bad. They got a new battery and as the guy behind the counter was new, a young lady rang up the transaction. She told him that if he rung it up a certain way that I'd be charged for the new battery based on what I'd paid 6 yrs ago and I'd save a bunch of $$. Cool! $60 is better than $106. After all was finalized and I was ready to leave she started telling the guy how my new battery warranty was based off my old battery. Huh? She said "yes that my new battery warranty would start where the old battery left off". So I said seeing as the old battery had a 6 yr. warranty, with 1 yr. left, that the new battery has 1 yr. warranty? she said yes. I told her to give me my money back, that there was no way I'd buy a battery with 1 yr warranty left on it. but she says "it'll cost you $106 for the new battery"(with a full warranty). I paid full price so watch it if this happens to you.
