I work at Advance on weekends, don't know who makes DieHard batteries but they don't seem any more reliable than any other battery. As for pricing, I think that has gotten way out of hand. I don't know how but JiffyLube gets them for $75 from us, retail price is $199. Hell of a markup, store employees don't even get that price.
And Optima prices have shot up anywhere from $50-130 in the last 6 months
