Odyssey batteries took a big jump in price.
Was in local battery shop today and they guy told me the popular Odyssey PC680MJ took a big jump in price. They used to sell it for $119 (when I got mine about 4 years ago) but now are at $163. Something about the military spec'd batteries, which the Odyssey PC680MJ is one such battery, all going towards to the war and a their need for a lot of lead too.
Just an fyi if you're in the market. Mine's about 4 years old now and it grunted yesterday on cranking like it had a stock BMW battery in it.
