Car Battery

So after 4+ years, my car (2008 Camry) battery seems to have died.
The dealer wanted $500 for a new one. That seemed a bit nuts.
I called a couple places locally and they didn’t sell the battery.
Online was better: $232 with shipping, but it would be 5 business days! Couldn’t wait that long.
Just told the dealer to go ahead and replace the battery after talking him down to $350, but the total was just under $400 after tax, labor ($10) and disposal ($3).
Then ISCA pointed me to Amazon: http://tinyurl.com/82nk7tp
$171, but still 5 day shipping. Oh well.
