6.4 Hemi first oil change

So i paid for my first oil change today on my 6.4 Hemi. I had the oil changed and the tires rotated and it cost me right at $103. Oil was $67 of it for 7qts and the filter was $10. Just wanted to let any 6.4 owners and future owners know.

I also wanted to know of a good place that I can order the Pennzoil ultra 0W40 synthetic oil for cheaper to do the work myself.
