Looking to replace the battery in my 2018 Ram 5.7. Napa has 15% offer right now, so I thought I would take advantage of the deal. When I look up batteries, all three options say "Eligible for 15% off", that is of course until you go to checkout. Shopping cart says 15% off is only for eligible items...I guess I'm remembering why I gave up on Napa years ago. Smh
