Also call around. I called 3 Honda dealerships and greg's Japanese Auto, inquiring how much will be valve adjustment for my Ridgeline. That is still under power train warranty.
GJA was - surprise - most expensive, at $600 before tax.
Dealerships went from $450 to $345 and the last promised to warrant it.
Also, look well into fine print with Gentec and such. 36 months you may get, but is it serviced at your doorstep?
It is well understood, why batteries cost so much to ship. It's not even seller, it's FTSA and NHTSA regulations.
If I were you, I'd have called salvage yards around and look for one from front end collision vehicle. Safe to buy.

 

The reason for this is that you get reimbursed for the price of the product bought, if it is defective, but not the shipping costs.
