Your conclusion is wrong. As many numerous posts have said, most if not all oil was purchased online or with sales, clearances etc….
I bought 12 5 quart jugs of Chevron Supreme from Walmart.com in 2020 because they were around $16 a piece. The shell rotella was from close outs from Home Depot. The Amsoil was when I bought two jugs and a case of Amsoil cvt fluid offline.
I’ve seen different Walmart shelves practically empty and then the next week full of oil. Like another poster mentioned, you go to auto parts store their shelves are always stocked because of their ridiculous higher prices
