Today? NO! I just now checked on the AAP site(where I make most automotive purchases) and they are both the same price per battery level(Silver-$179, Gold-$209, Platinum-$229, AGM-$239)
Yesterday? YES! In the past, when I have purchased the batteries for my vehicles at AAP or WM, the Group 35 was about $5-$7 more than the Group 24F(larger, more CCA/CA)... Not always but often.
Sadly, AAP doesn't allow any discount codes to be used on batteries. It even highlights this right next to the battery("Excluded from discounts except Speed Perks rewards").
