They have deka 9l,15l, and 16l in the 80s with a core charge at advance auto. But the 14l is 104 no core charge. Still cheaper than anywhere else with the discount.
For the ones in the 80s it is cheaper to use trt41 for two batteries in one purchase and turn in core batteries for a core charge.
If you want a 14l the cheapiest way to do it is to use trt30 on a single battery in each purchase which reduced it to 65 each. Then use the core batteries to get a 5 dollar credit there or whatever store offers it. No shipping to home though.
