Purchased a 3 gallon/12 quart box of synthetic 5W-30 some months ago for $20 during a rollback/clearance. Last weekend I changed the oil in 3 vehicles that use 5W-30. Bottom line is dealing with that box, for me, was a PITA coming and going and certainly extended the time it takes for an oil change. Primarily decanting and measuring the oil into an already empty 5 quart oil jug (thank goodness for the clear view quart markings on the side) and then the tortured process for getting the used oil back into the bag. Buying a SN Plus/dexos1 GEN2 oil for $1.67/qt. is nice but I'm a jug man for now on.
