My problem is with the shipping. By the time you pay that, you haven't saved anything, imo. Nothing wrong with the dealer. Nothing wrong with a Wix, NAPA, or local Farm Supply Store, which might sell Hasting, a good filter. Our local Family Farm & Garden does.
The oil is too heavy to pay shipping. Hard to beat WalMart prices on that. Rotella, Chevron, MotorCraft, Delo, etc. There also always Tractor Supply, but our local stores only stock Frams and you know how many guys feel about those.
