I'm the OP on this and here's an interesting development. I was under the impression that more expensive meant a better battery so I was about to go to XXXX, a pro auto parts chain and try to negotiate a better deal than the almost $150 I was quoted the first time I called. I think he said retail was about $25 more.
So I searched the battery on-line today and found the price at XXXX was now quoted at $122. Well, maybe the price changed in two weeks but that price change makes me uneasy.
It puts a whole new light on the XX Farm Store battery at approx $110. While I didn't check CCA's etc I now have to wonder if all these batteries aren't the same and the priced just depends on what the market will bear. Shopping seems to be a good idea.
