Yeah, because no one wants to save money!
Bought a quart of oil at auto parts store (popular chain) and it was $11. I did it because it my vehicle was in need. Twice. First and last. Went home and checked Amazon. $22 for 5 quarts! There’s a reason that Amazon was up $138/share yesterday.
True story. I order my motor oil from amazon in a 55 gallon drum.
its cheaper that the local propane/oil company and a dock truck delivers it right to the shop door.
