Oooh, it's been over a year. I can't remember if shipping was free or not. Actually, I think I did pay shipping but it wasn't too expensive because it could be sent regular freight, not hazardous materials like regular batteries.
FWIW, I did a boo boo and left the interior light on in my Jeep in the garage. By the time I noticed it, the battery was completely lifeless. I charged it up on the charger and it has worked as good as new.
