Boxes are interesting, though I do find the jugs handy for recycling the oil. I've found with boxed wine there is almost a full glass left in the bag no matter how I tilt the box. Be sure to check to get the last bit of oil out of the bag. Personally, I wish there were just a few standard sized containers so it is easy to compare prices. Probably 1 liter and 5 liter would be perfect, if we want to go metric.
