Nope, I tried that first. Mopar Direct gives you a small discount compared to most dealers, still almost double the price of Granger. All those stupid emails from Mopar about getting a discount amounted to barely anything.
Not my local dealer or Mopar Direct could match Granger. After purchasing the warranty from Granger, my Maximum care extended warranty showed up on my official Mopar Dashboard, showing all the details I paid for, nice and official.
Buying from Granger is a no brainer, unless you want to spend a lot more money for the exact same product. Nice to have that piece of mind for half the price I originally expected to pay.
