As already posted, hit your local Orscheln store. Your location says that you are in the Midwest, so perhaps you have one locally. Most Sams Club stores carry it, at least in the Midwest. Most Midwest WalMart stores used to carry this oil, but I guess Conoco-Phillips wouldn't pay WM for their shelf space, or the average WM shopper just didn't realize how good this budget-priced oil really is. I do know of one WalMart store in Lincoln, Nebraska that regularly carries TropArtic oil, but I suspect they only carry it because there is a Sams Club right next door to them. I've already walked into this store and had them price-match the Orscheln $1.99/quart sale price.
One more thing: Orscheln will also give a senior citizen, a military and an FFA-member discount, IIRC 5%.
