Petroleum Service Company?

Another thought is to find your local oil distributor, stop in and check their prices. Mine didn’t carry the Phillips oil I was after, but they were happy to order it in for me. I bought six cases and beat everyone’s prices at the time. This may not work for all, but you never know.

Or add 1 quart to your case order to get the total price high enough to get free shipping. That 1 quart is pricey but cheaper than the shipping it replaces. And the total 13 quarts is still cheaper than anywhere else I've seen, price all-in with taxes & shipping.

That said, ordering 2 cases is the most cost effective if long-term solution. You know you're gonna use it eventually!

In @Beachy 's case, they are 6 quarts per case.
They upped their free shipping threshold to $99, so more than one quart.

I've ordered from them. For a case of Phillips 20w50 they were pretty good (when you factored in shipping and alL)>
