aside from getting it replaced under warranty, reason it is tough to find batteries online is shipping is often a bit more than UPS or FeEx.
Local shops should be fairly competitive with battery prices. Even big box stores carry batteries. (Walmart, Costco, Fred Meyers), not to mention auto parts stores. Heck, even ACE hardware carries Interstate batteries.
One nice thing about buying local is that they often have already poured the acid into the battery for you. Although, the last battery I got from Walmart was a kit, I had to pour in the acid. Let it soak for a few hours and then slow charge it overnight.
Of course, for me, shipping to Alaska cost more than the battery, so buying local is always cheaper.
