I agree w/you but be prepare to be flamed by the "Influencers" on this board. I made the same statement & some here had a meltdown. They said "I made a bold claim & It's not be the same" & I argued "Why would NAPA pay for a special blend". HA! It makes perfect sense that it's exactly the same product in the bottle with a different label but I've not done or seen a VOA to prove me wrong yet.
Amazon & other retailers can be convenient no doubt about it. My only local retail outlet for anything is the local Wally. The joys of living in a cowtown, Mizzura LOL. I don't know for sure but I think that the oil suppliers rent the space & set the sale price promotions.
