This thread is hilarious. The Duralast Gold is essentially the same battery as the Interstate Megatron, and the Autolite Titanium at Advance Auto.
Here's the difference: When your Interstate goes bad, try finding a readily available business that sells them to the public. Most Interstate's are sold through repair facilities. You could buy the Duralast, have the 3 year free replacement warranty and 8 year pro rata warranty, and when it goes bad down the road, you'll be back up and running as you'll be able to find one of the hundreds of Autozone's across the country, and they'll install a battery for free.
So if you want to wait until Christmas is over, pay someone an exorbitant amount of money on an Interstate battery, and probably $100 bucks to clean the terminals, have at it!
Merry Christmas.
