Shopped at Sam's Club yesterday and they have Interstate 91's for $87.77 plus I have a $10. discount card from some promo. Makes the total bill about $83. tax incl. for a new Megatron. Just had my '04 inspected and had Firestone test the Varta and they said it had about one third CCA of original spec. They also wanted $173. for an H6 . I know they want to sell batteries but I think I'll replace it at Sam's before another Texas summer for $83 Oreilly's wanted $91+tax for their brand.
